[issue10682] With '*args' or even bare '*' in def/call argument list, trailing comma causes SyntaxError

[Raymond Hettinger]

Raymond Hettinger <rhettinger at users.sourceforge.net> added the comment:

The current behavior for function definitions is beneficial because a trailing comma in the argument list is likely to signal a real error (omitted variable).

In contrast, the trailing comma for lists is useful because entries on separate lines in a repeating pattern that makes it easy to add or remove entries.

The use cases for both function definitions and lists are best served by the current behavior, more so that a notion driven by "foolish consistency".

Recommend rejecting and closing.
