Slang looks interesting, I've been reading a bit about it over the last few weeks.

However, I've already run into the problem that, while it's a clever name for a shading language, it's a terrible name when trying to find anything in a search engine.

Making sure that devs can search and find answers quickly is an extremely important aspect of developer ergonomics, and I hope this issue isn't reflected in other subtle design flaws throughout the project.

A much less clever name that isn't already a common English word is always preferable. Call it xyzSL or something boring like that, which is unique and will always return meaningful search results.
