I started learning another programming language and noticed that after learning a certain number of languages, I've stop seeing individual languages. Instead I've started being able to memorize languages as variants of one I already know, which is insanely fast.

Most languages use a C based syntax, So internally I'm often just memorizing when and where they differ from C. Learning GoLang is especially interesting because most parts of it map directly to either C, Java, or Python.

There was one case where I was able to read and write a programming language I'd never seen before just by looking at some existing code and building an internal map.
