121. Re: Feature request : More lightuserdata types (score: 18)

Author: Flyer31 Test <flyer31@...>

So lightuserdata would just be a 64bit value (and in Lua32 then a 32bit value). And you anyway can use metafunctions with lightuserdata? ... this is a bit a surprise to me ... but sounds interesting

You probably want a full userdata to avoid UB. LU aren't collected, so you can't know if it's still alive or not/when to free it/etc. "Optimizations" like these are a security nightmare. Many object

If I understand correctly, all the objects should have a pre-known max size to meet the soft real-time requirements. I use Lua scripts to control the robot arm to grab cookies, plates, fruits and et

I think the middle ground here is to distinguish between Lua strings as byte arrays and UTF-8 as sequences of code points. Doing full-blown Unicode support is horrendous, but providing library functi

Only marginally I think. I/O as a text could be faster. Actually using a normal integer type is probably a better solution, I don't know why I recommended BCD.
