THANK YOU very much Javier for bottom posting your reply!

So a Lua string is like a string constant in C?

That does NOT make sense to me! The variable name, i.e. myName is
not changed. The contents of variable myName has been changed to
another string.

I get it that 'blah' and 'blah-blau' are 2 different strings and
are set in stone. But I don't see the point of even bringing the
subject of string immutability unless it's in the context of they
being constants.
