For CTFE: functions should be pure. Therefore you cannot use
global or static variables. Constants (enums) are perfectly
fine to use though. I don't know the state of the GC and CTFE.
I recall that there might be some complexity when using the
`new` keyword.

Basically the only limitation of string mixins is that a single
string should evaluate to valid D code, opposed to C macros. So
int y mixin("= 6");
doesn't compile, while
int y = mixin("6");
or
mixin("int y = 6;");
does. You can use CTFE to compose the string.
Ok, so mixins are really easy.
CTFE is the hard pard.
The link that you send me, i could not find it (or i haven't
tried hard enough). Thanks!
