[mekkkkkk]

Ironically enough I'd say extremely old-school imperative code has made a large impact for me. I've learnt OOP and to some extent FP as my default. Doing some OpenGL and other rendering stuff was refreshing and allowed me to explore much simpler ways to think about problems. Letting go of abstractions is tougher than it sounds. Killing your darlings type stuff.

I never really got into systems languages. I guess that's the main way other programmers get the same insights.
