I was thinking about using mixin templates to put some 
module-level default information in a single file so that it 
doesn't clutter up other files. It works for imports, but it 
doesn't seem to propagate for function attributes.

module_default.d
-------------------
module module_default;

mixin template module_default()
{
	import std.traits : functionAttributes;
	import std.stdio : writeln;
	
	 safe:
}

app.d
-------------------
import module_default;

mixin module_default;

int foo(int x)
{
	return x;
}

void main() {
	
	writeln(functionAttributes!foo);
}

Compiled with dmd app.d module_default.d on Windows 7 64bit. The 
output is system, when I would expect it to be safe.

I'm not sure if this is how the behavior is supposed to be or if 
it is a bug.

It's not a bug. The ` attribute:` syntax applies to all following 
declarations _inside the current scope_, i.e. until your mixin 
templates closing `}`.

I believe, however, that it _is_ a bug that the imported symbols 
are visible outside the template. Most likely related to the 
infamous https://issues.dlang.org/show_bug.cgi?id=314

Thanks. The fact that one worked and the other didn't was what I 
found weird.

It looks like this issue covers it

It appears that there is a pull request in the works to fix the 
behavior.
