* Count positional arguments before converting any
FuncArgs::bind_for rejected surplus positional arguments only after
FromArgs::from_args had converted every declared parameter. A
conversion can run user code (__iter__ for PyIter, __index__ for
ArgIndex), so filter(None, it, 0), hex(x, 1) and pairwise(it, 0) raised
whatever that code raised instead of the TypeError CPython reports
before it touches any argument.
Check the count against FromArgs::arity() before from_args runs. For
that bound to be safe:
- The default arity() has no upper bound, since a manual impl may take
positional arguments itself. KwArgs, (), DirFd, OpenDirFd and csv's
FormatOptions declare the bound they actually have.
- A derived struct adds the upper bound of each flattened field.
- A tuple sums upper bounds with saturating_add.
Assisted-by: Claude Code:claude-opus-5-5
* Note why arity upper bounds saturate
Comment that an unbounded upper bound is usize::MAX, which is why the
tuple and derived arity() sums use saturating_add, and drop the CPython
mention from the positional count check comment.
