Andrei Alexandrescu:
I don't think that compares apples to apples, as the entire
feature combination present into either language must be taken
into account.
I agree that features must take in account the specific ecology
of the other features of a language. And I agree the problem I am
discussing about refers to the idea of "main module" that is
currently ill defined in D (but I think it should be defined).
But the point is, I am desiring to solve this problem since years
in D, so far I have written tons of lines of D1/D2 code, and I
have not found a good solution.
I think for someone coming from Python, something akin to
if __name__ == "__main__":
main()
makes good sense. In my opinion that's not a design we should
copy.
I have suggested that solution just because I know it, and
because it's probably easy to implement (once the idea of main
module is defined). But I agree there are surely better designs
to solve this problem. But some solution is desired, that
Python-style solution is better than the current D situation :-)
Currently I usually solve that problem wrapping the main in
"static if (modulename_main)" and I compile with that version.
Bye,
