For what it's worth the Tango regexes actually have a method to output
a D function that will implement the regex after it's compiled.  So
you _could_ precompile the regex into D code and use that.

But seriously, man - if something takes 60 seconds to complete at
_runtime_, making it CTFE would simply make your computer explode.
