Can we get unitests to not run with program start ?

What would be possible is a "-fdmain" switch (force dummy main). 
Its role would be: if a functionDeclaration named "main" is 
present then this normal "main" is not used (technically erased 
from the AST or something like that). Then acts like "-main".

If I understand correctly the real problem happens when modules 
have to be tested but the real program "main()" must be skipped. 
All the other scenarios can be handled easily. For example an IDE 
can lookup in the AST and automatically add "-main" when the 
"main" declaration misses (and obviously if "-unittest" is 
defined).
