What about separating argument by commas, and treating each CSV as an
expression to be evaluated? The Python function would then receive
arguments as value objects.

This also means that convenience variables (and variables in the
inferior) would work.

The Python function would also return a value object.

I actually prefer the $func(...) syntax. Using $(func args) doesn't feel
natural for non-LISP hackers. The former approach IMHO fits better with
the current GDB syntax, and also with the imperative language used in
the inferior.
