Thank you Hector for your explanation.
I tested it in the Lua REPL:
myName = 'hector'
myName = myName .. ' vido'
print(myName)  => hector vido

So the char array "myName" has a new value. Correct?
and there is now an abandoned char array that contain only 'hector'?
which the gc will eventually destroy?
