The question as usual is, is the (at least as I see it) better
readability worth a little performance drop?
Also, the functions that are factored out could still be inlined by the
compiler (If we continue the use of the current switch-statement). AFAIK
some compilers already do if a function is only used once.
I just tend to prefer readability over speed, unless it's a REALLY
performance critical part. The expansion-language IS a central part of
exim, but does it need to "run like greased lightning"?
