I think I actually need that as well :). I would like to be able to
translate code like this:
typedef int foo;
typedef long foo;
alias foo = int;
alias foo = long;
Preferably I would like to do that without having to run the tool on
different platforms and somehow merge the results.
I know it technically violates the meaning of the source code. I'm just
trying to automate what a developer would do manually anyway. Doing it
manually just increases the risk of making mistakes.
