How should DMD detect if you're building a (dynamic) library? Sure it
can see that you're not using -lib or -shared but what about separate

What about the need to use a compiler switch if you are performing a
separate compilation?

A related enhancement request that I'm asking for since years is: the
compiler could define a compile-time constant (like is_main_module or
something) as true if the module contains the main, and false
otherwise. This allows to have a main() in each module. This is handy
to have, it allows to compile&run modules both as normal modules to
import, or to compile and run them as stand alone programs, like when
you want a module to show a demo of its capabilities, or just run its
unittests.

Yes, this is a nice thing Java, .NET and Python have.

Wonder if a simple convention would suffice, e.g. every module that 
wanna defines a moduleMain(string[] args) and then you have one module 
main.d that has:

void main(string[] args) { import wuddever; moduleMain(args); }
