Re: Question on Grep Function

@result = grep {$_ eq "a"} @array;

UPDATE: Yes, I can see that it differs from m/\ba\z/, they aren't at all similar in appearance. But there's no indication eq "a" isn't what he really wants and it's better in a few ways if that's what he's really looking for. Artist changed the trailing \b to a \z ... those are different too ...

`$_ eq "a"` is not the same as `/\ba\b/` or even `/\ba\z/` and is only correct within the limited number of examples given. It will break when given a string such as 'This is a' which probably should qualify. It is of course difficult to guess what the OP exactly wants.
