Array as LHS on string match

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

I humbly seek wisdom. Can I use an array (probably in list context) on the left hand side of a regexp match operation?

(@vals) =~ m/[$chars]/;
[download]

or more specifically:

(values(%hash)) =~ m/[$chars]/;

You're probably after grep, which will return the elements of a list for which an expression or block evaluates to a true value.	[reply]

`Applying pattern match (m//) to @array will act on scalar(@array) at / +home/scripts/x.pl line 51.` [download] It would of been quicker for you to just try it yourself.	[reply] [d/l] [select]

Yes you can. But it probably doesn't do what you want it to do. What do you want it to do?	[reply]

Fletch had it right. I was lookign for something like exists to work on values instead of keys (as in the second example using a hash).	[reply]

maybe this example could help... `my $line=' this or that '; my @patterns= ( $line =~ /\s(\S)\s(\S)\s(\S)/ ); print join('-',@patterns); # prints this-or-that` [download]	[reply] [d/l]
