The answer to those questions is usually found by profiling. Asking
people for what they think is slow is almost certain to give you wrong
answers.

That's interesting. I can probably give that a shot.
So you think that's a bigger cost than the CTFE code that generates the
strings?
I don't know. I just did a test with Derelict that needed to be
compatible with D1 and D2 and therefore used string mixins
Alright, well I've got a case of beer with your name on it if you can pull
it off! ;)
+1. I too am waiting for CTFE improvements. I am working on a DSL and with
the present limitations, it is impractically slow and memory consuming
while compiling.

Walter Bright:
tl,dr: CTFE started out as a glorified constant folder, not an
interpreter. An interpreter needs a different design.
And I presume a basic JITting interpreter for CTFE (like one in
LDC2 using existing LLVM JIT tools) needs yet another design.

Does this also imply speedups for static foreach loops? I've got quite
a few of those and they seem to slow down compilation a bit. I've had
a funny error message once saying there's an error on line ~50_000 in
15 matches
