It's rare to get measurable gains from __builtin_expect, and 
since there is no macro preprocessor in D, it's likely less 
verbose to just put the common case as the first branch since 
most compilers use that for static branch prediction (with the 
same effect on resulting machine code as __builtin_expect.)

Just my 2c.
