digitalmars.D.bugs - CTFE Memory Hogging Workaround?

reply "Maxime Chevalier" <maximechevalierb gmail.com> writes:
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).

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.

Please use D.learn newsgroup for similar questions, this group is 
not for discussions.

There are coding strategies to partially reduce the memory used 
during CTFE, but in general it uses lot of memory, sometimes too 
much. This problem is well known and Don is working on it and he 
has improved the situation a little, but it will take time to fix 
it well, possibly some months or more.

Currently CTFE is not fit for heavy computations.
