Re^2: When is a function call not a function call

That doesn't seem to work:

%  perl -we 'sub fn {print "$a$b\n"} print(sort(fn(0,0,1,2)))'
Unquoted string "fn" may clash with future reserved word at -e line 1.

I can eliminate the warnings by choosing a function name that isn't all-lowercase but, as the output demonstrates, the function is still called as a comparator, not a modifier of the input list.

Update: I was using perl 5.6.1. The parentheses trick works with 5.8.

It's good to know that 5.6.x is broken in this regard in case one of us is unlucky enough to be required to use a 5 year old perl distribution. :-) thanks duff	[reply]
