table.insert's middle argument is a major wart.

I've seen so many people (new users and experienced) make the mistake of:

table.insert(t, str:gsub("x","y"))

Which can be much more subtle when people have done the (common) alias of:

local append = table.insert

(and this is all because `t[#t+1] = v` is labourious to write if `t` is a complex _expression_)

And as for the naming, every
single function in the table module already deals only with integer
indices, so I don't see the point in renaming copy to icopy. If you
want to rename something, maybe we should rename the table module to
array.

I think that's come up a few times as a good idea ;)

But I'm not all that bothered by copy vs icopy

I can just see someone asking "why isn't it copying my non-numeric indices?"
