May I ask what the (&$@) in the sub declaration is for?

I like computer programming because it's like Legos for the mind.

It's a prototype. Without the prototype, you'd have to do `pie sub { CODE }, SCALAR, LIST` or `pie &func, SCALAR, LIST` With the prototype, you can also do `pie { CODE } SCALAR, LIST`	[reply] [d/l] [select]

Ikegami, I see you disagree with Damian Conway (as expressed in Perl Best Practices--pp 194-196 for those of you following from home). I wish I understood better the exact thought processes behind each of your approaches. Either way, yes, $^I is the way to go (or, if you really want to be a Boy Scout about it, use English, only without the evil regexp vars, and use $INPLACE_EDIT in place of $^I).

Another justifiction: `$INPLACE_EDIT` is "clearer" that `$^I`. If you don't understand the process set in motion by setting an appropriate value into this magic variable, via either alias; and what constitutes an 'appropriate value'; and what other pieces of magical context are required to make it all work; then you are going to have to look it up. And it is just as easy to look up `$^I` as it is to lookup `$INPLACE_EDIT`. And if you are familiar with the requirements and effect of setting a value into that magic variable, then `$INPLACE_EDIT` is no clearer than `$^I`. The former is in no way enough to explain what's going on, if you are unfamiliar with the operation. Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error. "Science is about questioning the status quo. Questioning authority". In the absence of evidence, opinion is indistinguishable from prejudice. "Too many [] have been sedated by an oppressive environment of political correctness and risk aversion."

I can't comment until I know to what you are referring. What is on those pages?	[reply]

Ikegami: Basically Damian says never prototype subs. I don't know how much I can type in here without violating copyright. Browser: What prior justifictions are there? I like computer programming because it's like Legos for the mind.	[reply]
