I would like to do something like
`
dmd --buildversion=fooCollection{"a", "b", "c"} -run app.d

...

void bar()
{
     static foreach(i; fooCollection)
     {
         ...
     }
}
`

The idea being that bar can be packed in a library and the 
program that includes this library can decide what parameters 
will be added to foo whitout any runtime overhead and ugly 
looking syntax.

Is something simular possible?
If not, could I achieve thesame result by including a file 
`programsettings.d` with some compile time constants in there 
whitout my library depending on it?

The normal way to do this would be to make bar a template and 
have the program that uses it pass these parameters to it as 
template arguments.

Why didn't I think of that?
It's just initializing a library, of course!
Thank you for your help and happy coding.
