Lua, a Misunderstood Language (2021)

i don't think that's true - lua stores sparse arrays efficiently. the table above should only have 2 slots allocated. see [1] or [4] for details on how lua implements sparse arrays.

You are right. This code runs just fine on both of these online Lua websites. local tab = {} tab[938388893] = "hi" tab[987383332] = "Hello"

for k,v in pairs(tab) do print(k) print (v) end

But when I try it using the Sol library (embedded in C++) it eats all my memory. Is it a Sol issue or a C Lua binding issue? Anybody know?

sorry, i'm not familiar with Sol. might be worth inquiring on the lua mailing list
