Is it possible to execute a function inside .d script that has no main function?

[BoQsc]

Here I have a file named: module.d

>import std.stdio   : writeln;
>
>void interestingFunction(){
>	writeln("Testing");
>}

There is no main() function since, I want to import this module, 
into another .d file.

( If I try to import and module.d does have main() function I get 
this error: )
> otherFile.d(13): Error: only one main, WinMain, or DllMain 
> allowed. Previously found main at module.d(3)





I would like to launch function "interestingFunction()" directly 
using rdmd.
Is it possible to achieve that by any way?





I tried to launch the whole file, but it gave me some weird 
output:
