I want to have many stand-alone programs that calls the common 
function.
Each app.d is its own separate directory so I can use the same 
name.

app.d
     static bool compileTimeFlag1 = true;
     common_func()

app.d
     static bool compileTimeFlag1 = true;
     static bool compileTimeFlag2 = true;
     common_func()

app.d
     static bool compileTimeFlag1 = true;
     static bool compileTimeFlag2 = true;
     static bool compileTimeFlag3 = true;
     common_func()


I've got this working, but only if I add an "import app;" to 
module_common.
Otherwise I get, "Error: undefined identifier compileTimeFlags

I want to keep all the compileTimeFlags in the main modules. 
Seems like the
most logical place to put them.

But it seems like I'm committing some great sin by doing this. 
Maybe it's my C++ days,
but it just seems wrong to have a module import the main module? 
Is there a more elegant
approach?


Just another quick question: is the module that holds the main() 
function just the
same as any other module?  Or is there some secret sauce?  
(Besides the point of entry)


Thanks.

meh i see no problem with it.

It is the same as any other module. I say it should be named the 
same as any other (including a two-part name, `module foo;` is 
likely to clash if you ever do two libraries, i almost always use 
`module myproject.foo;` instead), but all the exact same rules 
apply.
