__traits(compiles, ...) can't check if a declaration is valid
directly. You have to wrap it in a function literal expression:

No problem, make a full string then mixin it.
Your "no problem" = lot of string concatenation therefore slower and
memory hungry, i have no desire to do that
Do you think that string concatenation is
Ok, i'll just do it and benchmark at the end
Another question:
Why doesn't this work?:
```D
mixin implement;
mixin template implement()

char[4096] buffer = 0;
int pos = 0;
void append(string str)

buffer[pos .. pos + str.length] = str[];

String Mixins and Template Mixins are two different things. If you want

This limitation is very intentional, add it to the pile like file
io in ctfe of stuff that the core devs think "you shouldnt even
want that" for "safety"

please stick to what i wrote, i don't want string

everything should be a single template block, no extra
functions other than the append() one
Mixin templates are a declaration s
