This is becoming clear. Hopefully these patterns can be optimized across
modules eventually. It's easy enough to write a pre-processor that expands
the generics into four specializations. But it doesn't solve everything so
not a priority.

I'm trailblazing cross-platform OpenGL in Swift. Given there's only one
other platform, the key question is, "Does it work on Linux?"
Is your SwiftGL online somewhere? A cursory search didn't yield anything.
