Hi, everyone
Lua standard library do not provide "split" function, and there are a lot of implementations with different limitations, there is even a wiki about this topic(
http://lua-users.org/wiki/SplitJoin).
I've wonder since a "join"(table.join) function is there, then why isn't a "split" function ?
Seems the reason is just because trivial performance gain ?
I'm curious about more details (in my case(maybe not in common), "split" is commonly used and should be defined well).
And there is also a common(and big) question here : What is the basis of deciding which function should be added into standard library and which should not ?
