Which is similar to what Java does.

When i was first learning Java in a company i would make main() and have it run all the unittests of that particular module, then have a different file that actually combined all the tools together to run the program. Though when making the jar I'd specify which one actually was needed. But this was... 10 years ago.

For example, you could use a [version condition][1]:

module otherprogram;

version (Otherprogram_NoMain)
{
    // no main function
}
else

    void main(string[] args)
    {
        // ...
    }
}

// other functions...
