I was checking my repo occt.nim and some examples that used to work (or that is what I believe), now they stopped working.
For instance: gp_06_ax1.nim when compiled and run:
$ nim cpp -r gp_06_ax1
...

In fact, I am having some extrange behaviours with constructors. For example:

It looks like the commas were missing in the constructor.
I am on ArchLinux using Nim v2.0.2.
I think it worked before because it wasnt generating the right codegen. I recall fixing a bug related to mixing globals and constructor.
Please, fix an issue with a small repro and I will try to take a look at it soon.

Sorry about not providing a simple C++ repro. I don't know C++.
