- Paolo Invernizzi (5/25) Dec 09 2023 Same situation here, with RayLib!
Macros with the pattern:
#define BOO ( expression )
are now translated to:
auto BOO()() { return expression; }
and are available for importing!

It's still a C expression, and has C semantics. D templates with C semantics just falls out of the way ImportC was implemented.

Does this work for function-like macros?

This is amazing! It should solve the disappearing of enum-like
definitions in code. I encountered this in Raylib. It has colors
defined as macros:
```c
#define WHITE (Color){255, 255, 255, 255}
```
I preprocessed the file and all color definitions were gone. I
had to redefine them manually.
Nuklear does the same too for their Flags.
