I was talking about functions running at compile time. In D that's 
handled by an interpreter which doesn't support the full language. It 
also behaves differently from the "regular" language. Bugs occur in the 
CTFE interpreter which doesn't occur in the regular compiler.

In Scala it _is_ the regular compiler that handles both the CTFE and the 
regular code. A bug in the regular compiler will show up during CTFE as 
well.

BTW, how do you make a string mixin hygienic?
