Re: Thought experiment: what would you remove from Lua

["John Hind" <john.hind@...>]

Definitely 'ipairs' and the metamethod on 'pairs'. The former is usually 
better done using numeric 'for' and can be trivially implemented in Lua 
if wanted. The latter can be done by replacing 'pairs' or by writing 
another iterator with a name reflecting what it does.

Generally I'd remove everything from the standard libraries that does 
not justify implementation in 'C' either because it cannot be done in 
Lua or because serious performance gains can be had. Then I'd have 
standard Lua implementations for the rest.
