map is not the correct solution since it does not filter out those which
do not match the pattern. Only grep can do that.
my @selected = map { /before(pattern)after/ ? $1 : () } @all;
no need for the ?: as list context will grab $1 or nothing. see my other
post for a working one liner that shows this.
The context changed, because of the "Only grep can do that.".
Each way has it use.
