Re^2: map and grep one-liner problem

This is really getting close to unreadability :)
There is one thing in the first printf that I don't understand: index $_, $key . ' '
What exactly does the last part do ( . ' ' ), adding a space ? why ?

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` ?)	[reply] [d/l] [select]
