Top posting to nobody in particular.
I was arguing something about lengths or arrays at some point. Some helpful Lua List member kindly pointed something out to me:
Lua does not have sequences. It only has tables.
To put a positive spin on it: Lua has tables as it’s only data structure, at least as of 5.4, which will eliminate the limited ... (perhaps helped along by threads like this).
There is nothing that can’t be represented as a table and if you want something fancy, you have userdata. Adding sequences solves no problems.
“One data structure” is one of Lucas most important traits. I recommend learning to enjoy it and to play with that beautiful limitation.
