I think it will help somewhat, but it depends on your application. You 
can try the -lowmem switch which turns on the GC in the compiler. This 
should alleviate CTFE memory problems.

In my case (I've been running into this recently), I was running out of 
memory not from CTFE, but from template instantiations. Every little 
template allocates some space in the symbol table which never goes away. 
See my post here: https://forum.dlang.org/post/qrjls8$13je$1@digitalmars.com

Oh, and BTW, very much looking forward to newCTFE!
