Description (Last modified by JarrettBillingsley)

Python has the (kind of odd) "if __name__ == "__main__":" to determine this. It'd be nice to have.

I know that trick of python, however, i don't really like the way they implemented it. IMHO it is somehow ugly. I bet there are better ways to implement it, maybe something like: 

main function(vararg)
{
//...do main stuff here...
}

So that you add the keyword 'main' for a new function literal, which creates an anonymous main function, which is not executed, when the module is just imported. To go with that, you could maybe add a runMain([module]) function to he Stdlib. What do you think about it?

Sorry I never got back to this. I agree that the Python way of doing it is terribly unintuitive and ugly. I'm thinking that this could be done entirely without language changes, now that you've suggested the runMain function. runMain would just look for a global function named "main" in the given namespace, and run it with the (optional) varargs.

I really like that idea :D
