Re: (localtime)[3] vs. ((localtime)[3])

Actually, you don't have to enable warnings, as the construct won't compile:

    $ perl -wle 'print(localtime)[3]'
    syntax error at -e line 1, near ")["
    Execution of -e aborted due to compilation errors.
    $

The warning you are referring to is silly. It'll trigger in constructs like:

    print (3) + 4
[download]

but only if you have a single space between 'print' and the opening parenthesis.

And you thought Python was evil because it gave meaning to whitespace.

Initialize only two persons reacted, one was in favour of removing it, one was against removing it. So, I provided a patch, and that got more reactions. Some in favour, some against. That's of course enough reaction to not have the patch accepted. Rafael suggested that it's possible to inspect the op-tree and determine whether 'print' is used as an operand in a boolean function, and to issue the warning only then. After a well Hugo responded we though that was a good idea, and if someone would implement it, he would accept it. So, there is a tiny chance that in a few years, the warning won't give so many false positives anymore. I also got the impression that the people who were in favour of keeping the warning are people who don't write a space between the function name and the opening paren, while among the people in favour of removing the warning were people who do put a space there. But I have the patch, and from now on, I'll patch any perl I install so that it won't issue the warning. Abigail	[reply]
