Then the next question is how to support the very common case of print *, a, b, c (Fortran) and print(a, b, c) (Python), where the print formatting is automatically set based on the types. One could do that using:
- | StringFormat(expr fmt, expr* args, string_format_kind kind, ttype type, expr? value)
+ | StringFormat(expr? fmt, expr* args, string_format_kind kind, ttype type, expr? value)
Where if the "fmt" is not present, the arguments will just be printed based on the kind argument. Regarding separator and end, those are rare cases, and I would just create an explicit format string in those cases, and not special case it in any way.
