I was under the impression that the extern (C) function rt_init() would 
magically be exposed from the library but 'nm' showed no such symbol. 
So, I ended up exposing a my_init() function, which called rt_init() 

I've realized that rt_init() is sneaky: it returns 1 for success. WAT!? 
:p Then I discovered the more readable Runtime.initialize(), which is 
also sneaky by returning 'true' for success. WAT!? WAT!? :p

This worked:

import core.runtime;

extern (C)
int my_init() {
   return tried({
     return Runtime.initialize ? 0 : 1;

my_deinit() is similar...


P.S.'tried' is a function template that I wrote, which catches all 
throwables, logs the issue, and returns 1 as an error code.
