I will try it.
http://swtch.com/~rsc/regexp/regexp1.html, it could be a starting point,
Before fully embracing the contents of that page, look at its critics too.
3) When I saw Don's comments on fixing CTFE, I remembered something D
can do _better_ than most others mainstream compiled languages -
metaprogramming. So having a StaticRegex compiled at compile-time
(inevitable calambour) would give us an edge over comparative
implementations.
But it inflates the binary too, if overused, because each RE pattern becomes a
compiled function (or more than one).
Another thing to sort out is style: are we sticking with ECMA or
switching to Perl / GNU? Shall we provide also different versions of
syntax?
One RE syntax in a language is more than enough :-) But there are some features
of the Python REs that I'd like to see bolted-on to the ECMA REs used by D. So
I suggest a superset of ECMA.
... especially the ability to insert free spacing to clarify / comment the
string pattern (meaning literal whitespace is escaped like '.', etc) (dunno if
D regex supports that already though).
