Is there a standard library, where code like that belongs to? (I think
it's Ok, that it isn't part of the *language* itself, so the language

exchanged/shared among developers. Just: take it all or nothing.
Yes, rolling your own is the style of the house:
local function Copy( aValue )
if type( aValue ) == "table" then
local aCopy = {}
for aKey, aValue in pairs( aValue ) do
aCopy[ Copy( aKey ) ] = Copy( aValue )
end
aValue = aCopy
end
return aValue
end
But... as both Manel and Doug have pointed out, there are many
resources for you to peruse for inspiration:
http://lua-users.org/wiki/StandardLibraries
http://sano.luaforge.net/
etc...
Lua is a bit like an, hmmm, "auberge espagnole"... you get mostly what
you bring in... :P
