Prefix variables and functions

[yilinwei]

Unlike racket, ELisp doesn't have namespaces unfortunately. The top-level is typically reserved for Emacs provided functions. Unfortunately, with a top-level global namespace you can run into issues without prefixing quite quickly.

The community has a convention of prefixing their functions with namespaces; double-dash for private functions and a single dash for public one. For example, straight might expose a function like straight--private-thingy and straight-public-thingy.
