table.insert already has an optional middle argument, I don't see any

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
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?"
