In the face of ambiguity, refuse the temptation to guess?

I guess because it is not clear what (1, *(2, 3)) should mean. 
Parentheses when used for function call has different semantic then when 
parentheses is used for tuple syntax. Parentheses in function is part of 
the calling syntax, while parentheses in tuple is used only for grouping.

PS: anyway I just realized that since tuple is immutable, having (1, 
*(2, 3)) be (1, 2, 3) would violate immutability. Maybe a list would be 
a better example.
