Searching lists to select elements based on a specific criterion is a fairly common task--will Grep make that task easier? What do you think? Tell us about your experience with this function.

TIMTOWTDI(There Is More Than One Way To Do It).
In fact in Perl alway there is more than one way. Like
@a = grep {/smth/} @a - will give you all that have smth.
@a = map {$_ if /smth/} @a - is doing just the same.
And this can be done with for,foreach statement for(@a){},foraech(@a){}.
This is the BEAUTY of Perl;-)))
