Not yet :)
I assume it would bring the current system to it's needs.

I you want to experiment you could replace malloc with new.

CTFE using of replaceAll from std.regex posible?

[Martin Tschierschke via Digitalmars-d-learn]

Hello,
when trying to process an string at compile time with
 ...
 auto reg = ctRegex!`as\ [a-z]+`;
 enum replaced = replaceAll(call,reg,"");

I get:

available source code

It there a way to use "replaceAll" at compile time?
