I was meaning that with out the \b (to escape word boundaries) "Ba" would match Bad meaning 


$match = 'Ba';
@array = ('Bad','Good','Whatever');

if (grep(/$match/, @array)) { print "Yippie!\n"; }
else { print "No Match\n"; }

If you enclosed the variable $match in word boundaries as followed

grep(/\b$match\b/, @array)

It would no longer match do to the fact that the match must match the exact string passed
