Hi fellow monks! I just stumbled across a pehaviour of perl 5.8.0 I can't explain to myself.

I first wanted to write: 

while(<>) {
    chomp;
    push(@{$para{$_}}, $ARGV);
}

[download]
but then wrote instead 
chomp,push(@{$para{$_}}, $ARGV) for (<>);

[download]
because it's shorter.

Unfortunately both versions are not equivalent. $ARGV is always the $ARGV[$#ARGV] in the for loop, while it changes to the current filename in the first loop.

Is this a documented feature?
