in reply to Scalar function

If $fa, $fb, and $fc are file handles, then

print CSV $_, scalar <$fa>, scalar <$fb>, scalar <$fc>;
is doing the equivalent of
my $line_a = <$fa>; my $line_b = <$fb>; my $line_c = <$fc>; print CSV $_, $line_a, $line_b, $line_c;
Note that there is no chomp on the reads from the three files.

[Lady_Aleena]: Has anyone here ever use pcregrep? I can't seem to get the --include regex right. --include=*.p[lm] works in grep but not pcregrep.
[erix]: to lift your spirits, here is some more happy Randy news...
[Lady_Aleena]: The reason I would like to use pcregrep is because it can do multiline searches supposedly.
[perldigious]: What are your criteria for looking Tanktalus? What things must a job have for you to consider it? And where are you in your career? Start, middle, or end?
[erix]: are there any regex-engines that do not do multiline?
[Lady_Aleena]: erix, grep doesn't.
[Lady_Aleena]: Linux grep that is...
[Lady_Aleena]: $ grep --include=*.p[lm] -Ern 'get_(array|hash| data)' does not do multiline search.
[Discipulus]: focus on Perl LA; you can already search multiline patterns
[erix]: grep is a program, not a regex-engine
