What's your issue about?

Is this a bug?
I can compile contract with *args and kwargs:
@public
def test1(a:uint256, *args,kwargs) ->bool:
return True

And if i try to get args, for example, i''ll get following error "Undeclared variable: args"

How can it be fixed?

Check for * and ** in fun declaration

@jacqueswww Maybe this highlights the case for a custom grammar. That kind of thing really should be a syntax error.

@davesque yup.
