I'm surprised to see only grep examples with "eq". You can also do this with regex interpolation (being careful to match the whole thing, of course):

print "found!" if grep(/^$e$/, @a);

This might be useful if, for example, you didn't care about matching case:

print "found!" if grep(/^$e$/i, @a);
