What is the exact problem statement?

 // Works:
 auto r = regex(r"/api/places/(id|related|search|count)\.(json|xml)", "g");

( it's not that simple ;) )

But it's "been there, seen that". In short:

 assert(this.ir[cast(ulong)orStart].code() == cast(IR)129u) failed

 assert(this.ir[cast(ulong)orStart].code() == cast(IR)129u) failed

A well known problem search Bugzilla with cast(IR)129u and you'd find 
it. Or just ctRegex.

And that's something I need to ping Don about. CTFE is still not 1:1 
with normal D.
