in reply to Re^2: The "<" in the grep block
in thread The "<" in the grep block

I agree that

@ARGV = map{glob} @ARGV; ....
does work, however, I think since "glob" can do the expansion, why not use
my @smaller_than_1000 = grep { -s $_ < 1000 } glob("@ARGV"); ....
see glob for detail.

If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.

    That works for this application, but wouldn't for the more common uses:

    BEGIN{ @ARGV = map glob, @ARGV } while( <> ) { ... }

    And

    perl -eBEGIN{@ARGV=map{glob}@ARGV} -nle"1" a*.pl b*.pl

    With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
    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.

    RIP Neil Armstrong
