Unfortunately I'm not able to help you with mir-ion. But I see 
two questions here:

I believe this is the case for the most languages - keyword is 
not allowed as a variable name.

IMO having `version` keyword in D is unexpected language design. 
No one will complain about keywords that are widely used in the 
industry (like `struct`, `int` etc). But `version`?! I hit this 
problem multiple times already and the only solution for me was 
to use `version_` instead.
