Yep, it was tremendously correct to start with (iirc) 'assert_eq' and 'print' as the two first statements in my language when building out the compiler. It meant I could start writing a test suite and assemble a larger and larger set of functionality as I went.

But I think other parts are probably harder, like getting type system stuff right.
