CTFE Memory Hogging Workaround?

[Maxime Chevalier]

One of the reasons I chose to use D for my project is that I was 
very excited about the prospect of using CTFE in mixin code. 
Unfortunately, there seems to be one (or several?) bugs causing 
CTFE to be very slow and to hog a huge amount of memory (multiple 
gigs of RAM and swap). I use the latest dmd and my mixin code 
uses an Appender!string object to produce a long string of D code 
containing multiple functions (~1500 lines).

Is there some known fix for this? I need this to work now. 
Otherwise, I'm going to have to rewrite my CTFE/mixin code in 
Python or something, which would be a shame, and a waste of time 
on my part. This is not the first compiler bug I run into, and 
I'm starting to regret not implementing my project in C++ instead.
