Execute a code variable for callback?

[Troll-Brain]

there is no best solution.

for single run we can use enum
for multiple static calls we can use trigger

with vJass we dont have control over code, its just like GUI

i cant cache evaluate calls for futher use, cos vJass decide what and how to do, not me.
95% of users enjoy this by using GUI, vJass, cJass, zinc or some system they dont ever understand.

Blah, end of the word i guess.
You never change your mind.
Yes vJass code handling is crap but it's the most beautiful generic crap at the moment, at least for this example.
And no i don't include myself in the 95 %, i'm perfectly aware about which jass2 code vJass generate.

Anyway, it's always nice to talk about alternatives, and let people choice what they prefer.
