Don't raise so much FUD about map, tilly! It's only slower in the current releases when the output array is larger than the input array.

One-to-one or one-to-less-than-one mapping is still quite fast: as fast as using a grep (on which the map code was originally based).

What was improved was the less common but equally useful case of one-to-more-than-one (more outputs than inputs), and that speedup code is in 5.7.0 and soon will be in 5.6.1 (about a month, I'm hearing from P5P).
