UB issues in C is way overblown. Just don't do dumb shit with null pointers and use const where appropriate that eliminates most of it.

As for other stuff, I was working on a LLVM extension a while back to put a lot of Python-isms into C, like the array slicing, print statement, f strings, and decorators.

Generally though, I found that writing your own macros is actually easy, and you just have to type stuff out a bit more. Last project I worked on in C I had an include file that had all the macros and the defined functions to go with the macros. The print statement honestly takes up most of the file, cause its a combination of vararg in the macro with _Generic selector with functions defined on how to print each type of variable. But the rest of the stuff like array slicing is just a macro that calls a function that takes the slice arguments as a string. Doesn't look as nice as actual array slicing, but it works and easy to write.
