BMPL: The language I'll bring to life
Last year, I started working on a language I named SuperCode but then decided BMPL (Builder's Multi-Purpose Language) as the final name. The language would be written using C and up until now, the GitHub repo only consists of a library of functions.
I decided to bring up the language onto Codidact's chat and have even started using it as some programming language, where I'd access the functions and assign them in TIO. To this day, I'd continue making answers on Code Golf CD using the language which is, until now, a library of libraries.
For this review, I want to know anything that can be improved with the functions and what could be fixed from what I made. I'm certain all functions I made before 2021 (all libraries except
is_type.h) work properly ever since I tested them.
Here's the most commonly-used function I have:
#define say(X) printf(_Generic((X), \ double: "%f", \ float: "%f", \ char *: "%s", \ int: "%d" \ ), (X));
