Re^3: RFC: Is there more to alias?

[xmath]

I think I've fixed the problem, and I've uploaded a fresh version. See if this helps.

As for your original questions.. I have read your original post several times, and I have honestly no idea what you're trying to accomplish....

for alias my $line (<DATA>) {}

This is a syntax error. And "for" already aliases, so what's the deal here? On top of that, why would you need an alias to the temporary var that contains the line anyway?

alias my $line = <DATA>;
while ( defined( alias my $line = <DATA> ) ) {}

These work, but again I don't see the point.. why alias $line to the read line? To prevent copying the line? I think perl already optimizes that away.

Maybe I'm just missing something, in which case please enlighten me.

Thanks, I'll try the new version.

And I don't think you're missing anything... hope I didn't make you spin too many cycles on that.

As I said it was a curiosity: A way to give $_ a 'pretty name' in a for or while loop. You're saying it's already the same to do:

for $line (<DATA>) {}
# or
for alias $line (<DATA>) {}

Ok. /shrug. I naively saw the named subroutine arguments as roughly the same thing. I am enlightened. =)
