in thread map and grep one-liner problem
What exactly does the last part do ( . ' ' ), adding a space ?
Yes, that's exactly what it does. Otherwise, as johngg points out above, a search for 'b' will match not just 'b', but also, for example, 'bbking'. And if you look closely at this line in Anno's solution:
my @values = map / (.*)/, grep /^$key /, @ta;you'll see that he does the same thing (note the space after ^$key ?)
