FIX2INT does not call to_int where int and long have the same size, so `method(:puts).curry(1r)` waited for a garbage number of arguments on Windows. Convert the arity once and keep the result as a Fixnum, which also limits the to_int call to one.
[Bug #22321]
In the following script, the klass of the Method object is an iclass, which
will raise an error "NoMethodError: undefined method 'inspect' for an instance of M":
module M
def foo = 1
end
class C
include M
end
obj = C.new
meth = obj.method(:foo).unbind.bind(obj)
puts meth.inspect
Method#unbind clones the method entry, preserving its defined_class.
For methods mixed in via include/extend, defined_class is an ICLASS,
causing UnboundMethod#== to return false when comparing against the
same method obtained via Module#instance_method.
Resolve ICLASS defined_class in method_eq.
[Bug #21873]
to fix inconsistent and wrong current namespace detections.
This includes:
* Moving load_path and related things from rb_vm_t to rb_namespace_t to simplify
accessing those values via namespace (instead of accessing either vm or ns)
* Initializing root_namespace earlier and consolidate builtin_namespace into root_namespace
* Adding VM_FRAME_FLAG_NS_REQUIRE for checkpoints to detect a namespace to load/require files
* Removing implicit refinements in the root namespace which was used to determine
the namespace to be loaded (replaced by VM_FRAME_FLAG_NS_REQUIRE)
* Removing namespaces from rb_proc_t because its namespace can be identified by lexical context
* Starting to use ep[VM_ENV_DATA_INDEX_SPECVAL] to store the current namespace when
the frame type is MAGIC_TOP or MAGIC_CLASS (block handlers don't exist in this case)
Previously, ruby2_keywords could be used on a method or proc with
post arguments, but I don't think the behavior is desired:
```ruby
def a(*c, **kw) [c, kw] end
def b(*a, b) a(*a, b) end
ruby2_keywords(:b)
b({foo: 1}, bar: 1)
```
This changes ruby2_keywords to emit a warning and not set the
flag on a method/proc with post arguments.
While here, fix the ruby2_keywords specs for warnings, since they
weren't testing what they should be testing. They all warned
because the method didn't accept a rest argument, not because it
accepted a keyword or keyword rest argument.
There is no need to store the symbol and the proc given the
proc has a reference to the symbol.
This makes the cache half as small, now fitting in an object
slot, but also make it easier to allow that cache to be
used by ractors, assuming we'd make `Symbol#to_proc`
return a shareable proc.
In non-main ractors, don't use `sym_proc_cache`. It is not thread-safe
to add to this array without a lock and also it leaks procs from one
ractor to another. Instead, we create a new proc each time. If this
results in poor performance we can come up with a solution later.

Forwarding argument is optimized not to packed when no other arguments
and an internal object refers values before it. This size is decided

point.
[Bug #20950]
ifunc proc has the ep allocated in the cfunc_proc_t which is the data of
the TypedData object. If an ifunc proc is duplicated, the ep points to
the ep of the source object. If the source object is freed, then the ep
of the duplicated object now points to a freed memory region. If we try
to use the ep we could crash.
For example, the following script crashes:
p = { a: 1 }.to_proc
100.times do
p = p.dup
GC.start
p.call
rescue ArgumentError
end
This commit changes ifunc proc to also duplicate the ep when it is duplicated.
To simplify the implementation, this makes Object#singleton_method
call the same method called by Object#method (rb_obj_method), then
check that the returned Method is defined before the superclass of the
object's singleton class. To keep the same error messages, it rescues
exceptions raised by rb_obj_method, and then raises its own exception.
