I don't understand, could you elaborate a bit ?

Hmmmm. Sounds good at thinking but another thing I wonder is how is this 
approach
is in action when trying to implement it as a developer. Not having macros and 
`#include`
and stuff would probably be better. Instead we could have templates that have 
to be
declared before used and then the compiler will see what it needs to generate 
and what
it has already been created. Of course a function will be a little bit slower 
than a macro
that will place the code in place but of course the difference is more tiny 
that TCC ;). `#if`
is the only one that makes sense tbh but it needs to be more powerful of course.
