You can look at the code in the first commit Linus made. It is a very minimal yet functional version of Git.

Edit: To get to this commit run

  $ git log --oneline --reverse master | head -n1
  e83c516331 Initial revision of "git", the information manager from hell

Linus describes this and more in his book - Just for Fun: The Story of an Accidental Revolutionary. Great read

This, exactly!

I had the same reaction initially but then realized that this makes the variable declaration / initialization syntax very consistent.

  variable: Type [= initial_value];

  // initializes foo to an int with an initial value of 43 
  foo: int = 43;

  // initializes main to a (presumably, as I haven't read the
  // spec yet, const)pointer to a function that takes no 
  // arguments and returns an int.
  main: () -> int = {
     ...
  }

One commit with as many parents as merged branches. (A git commit can have an arbitrary number of parent commits.)

Thank you!

Mind sharing the name of the course?

Yes. In the Ruby VM, an RVALUE [0] is a union (a "generic type") of structs that represent all the different kinds of Ruby object types and a couple of runtime types.
