Regex in ctfe?

[Era Scarecrow via Digitalmars-d]

  What exactly are you trying to do i wonder?

  If it uses enough of a subset then maybe... I'll assume you 
tried and failed already though.

  It seems more likely that a external library like PCRE would be 
compiled into the compiler instead and you could hook into it; 
But with probable mismatches of the Regex engine and features I'd 
wonder if it would cause problems (at least until the compiler is 
converted to D and can implement it's own d libraries).
