It's almost to 3 times slower. Minimal build time(when nothing is
actually built, only dependency checks are done) is 8 sec. with
include_regular_expression vs 23 sec. without one.

Yep, I'm already using it. I haven't noticed any great speedup though...

Is it possible to turn on some debug info showing which paths matched
include regular expression and which didn't? This
include_regular_expression thing is a real black box :D
