variables spanning modules?

I need to capture a small amount of program data and deal with it 
in termination signal handlers. The data will be captured from 
various classes spread around different modules.

I'm thinking the easiest solution is a couple of global vars and 
then i can access these in the signal handle after the various 
objects update these values during runtime.

Thoughts?

Why don't you use a __gshared module-global var, and then import 
it in all the modules where you need it?

I've just been looking at that but a little unsure how to use it. 
Do you import the module that declares the __gshared var or 
import the var itself?

Import the module then use the variable.


module globals;

int a; // or could be __gshared if you don't want it to be thread 
local


module test1;

import globals;

a = 10;


module test2;

import globals;

assert(a == 10); // ok because we set it in test1
