I've asked for this once but I didn't get satisfieing answers. My 
problem is this static opCall; I had to use the profiler in order to 
find the fastes implementation:
the static keyword makes the creation of the return struct up to 200 
times slower! I used obj2asm and the profiler to find out that the 
creation of the internal return value isn't "optimized away" at all.

Another thing that hurts is that an easy operation like 
assignment/cast/initialization to a struct have to be implemented 
through an opCall; Why do I have to assign each value manually to a 
struct (if I don't/can't implement a static opCall)

merry christmas!

Just a quick question: what compiler flags did you use, and what code 
did you use?  I did some analysis on generated code a while back, and 
the different compiler flags produced wildly varying results.

(Also: obj2asm?  You're lucky.  I had to use ndisasmw and magic numbers 
littered through the code :3)

I used -O -inline -release -profile and some of those build switches, 
but those shouldn't change anything
