From time to time I've been good enough to think I'm a master of a language. But that skill fades so fast. For some reason the mountains of trivia just sort of fade away without pretty regular use. Once upon a time, I could tell you all the semantics of `static` in C, but now I couldn't even give an accurate count of all the ways it's overloaded. There's like the top level declaration that sets aside memory, there's the declaration in a function that has slightly different initialization rules and is good for coroutines. And like, 4? more meanings in different locations. I only hit that level because of a compilers class. I feel like I could ramp back up, but the subtle nuances just sort of flit away like butterflies. More than 2 seems really challenging. Even simple stuff there's not much to scheme, but try getting a chez runtime running on a raspberry pi, and really understand the impact of the flags you build with and run with. Not easy (for me) to stay really sharp with that. I mean, sure, I can bang out some code. I can pattern match well enough that code I contribute blends in with the style of a project. But mastery? That's a big lift.
