Case insensitive vector indexing?

[petrihakkinen]

I find it unusual that vector indexing is case insensitive while everything else in Lua, table indexing in particular, is case sensitive. I'm probably going to disable that feature for consistency in our version, but I'm wondering should this be added as a config option to the official version too? Out of curiosity, why case-insensitive indexing was chosen?

Historically vectors on Roblox platform (predating the native vector type) allowed both cases; in Roblox the "dominant" (more idiomatic / used mostly) case is XYZ so technically the fast path could have just included the upper case but likely many non-Roblox embedders would have preferred xyz so we kept the case invariant lookup in the fast path.

Ah, so it was the other way around. I thought lowercase was the dominant one. Thanks for the answer.
