 ## The Core Library
 
-One of the unfortunate consequences of the way OCaml's compilation works, is that there is a library called the core library, documented [here](https://ocaml.org/manual/core.html), which contains some definitions for types and exceptions, yet does not include the code from the stdlib that uses them. When compiling with the `-nopervasives` flag, this is still included but without the standard library. While this makes sense from the perspective of having some fundamental exceptions always available, having types like `list` included makes it very annoying when implemented a custom standard library. This quirk is why my library has no type definition for `list`, `bool`, `option`, etc. but still uses these types.
