Re^6: wantarray - surprise behaviour

But they don't create lists. They are 'required' just as they are in some cases required to call a function correctly. That doesn't mean parens call functions. In the case you describe, parentheses are used for precedence:

perl -MO=Deparse,-p -e"@a = 1,2,3,4,5; print @a"
((@a = 1), '???', '???', '???', '???');
print(@a);
-e syntax OK

A list is still created - it's just not the list you want.

Which goes to demonstrate that saying that , and => builds lists is not enough. Just as parens are often required to clarify the programmers intent, so mentioning parens, and precedence is required to clarify the language's definition of a list.
