digitalmars.D.learn - Behavior of __FILE__ in mixin template

Hi,

I thought a mixin template is copied into the place where the 
mixin statement
exists and then the coding is evaluated.
This seems not to be true for __FILE__

I have a module form, which has a class Form. This module also 
contains
following mixin template

mixin template formTemplate()
{
	void generateForm()
	{
		string getFormName(string file =  __FILE__)()
		{
			import std.string: indexOf;
			return file[0..file.indexOf(".")]~".frm";
		}

		enum fileContent = import(getFormName());
	}
}

In another module myform I have a class MyForm in which I call 
the mixin statement:
mixin formTemplate.

The purpose of the template coding is: The enum fileContent 
should contain
the text of a file, which has the same name as the module but the 
file ending .frm.

I tried different things, but either it doesn't compile or 
__FILE__ returns "form"
instead of "myform".

Is this behavior correct? Do you have any tip?

Kind regards
André

Apparently its the whole template that supports that. Is moving the 
'file' parameter to the entire template acceptable?

mixin template formTemplate(string file = __FILE__)
{
     // ...
}
