toc improves on C's syntax (and semantics) in many ways, To declare x as an integer and set it to 5, you can do:

-x := 5; // Declare x and set x to 5 (infer type) -x : int = 5; // Explicitly make the type int. -x : int; x = 5; // Declare x as an integer, then set it to 5. +x := 5; // Declare x and set x to 5 (infer type)
+x : int = 5; // Explicitly make the type int.
+x : int; x = 5; // Declare x as an integer, then set it to 5.

Why?

This improves compilation speeds (especially from scratch), since you don’t have to include headers a bunch of times for each translation unit. This is more of a problem in C++, where, for example, doing #include <map> ends up turning into 25,000 lines after preprocessing. All of toc’s source code, which includes most of the C standard library, at the time of this writing (Dec 2019) is only 22,000 lines after preprocessing; imagine including all of that once for each translation unit which includes map. It also obviates the need for fancy build systems like CMake.

Just send me the toc source code which results in the bug, and I’ll try to fix it.
