Ternjs with Neovim

• upgrade nvim (in my case, I have the master version):

$ brew tap neovim/neovim
$ brew reinstall --HEAD neovim

• check Python 2 and 3, if are installed:

$ which python2

Mutual recursion

Every finete state machine that does not need to hold state can be represented by a mutual recursive pair (or more) of functions.

ML specific

You can implement mutual recursion using the built-in and keyword between functions. It is also possible to implement it using a higher order function (a function that receives another function).

SML Module System

There is a way to define a namespace in SML: define an "structure" that creates a module.

Example:

structure MyMath =
struct
val pi = 3.141529
