But you said that constants can be overriden and the name rebound.
Is your proposal only to add a keyword "constant" that does absolutely
nothing? If that is not your proposal, please explain what you want the
keyword to do. So far you have just confused me, and I don't think I'm
the only one.
You have said that constants can be rebound to new values, but then you
say they are used to stop them from being overridden.
You said that constants act just like literals, but you won't tell us
how literals act.
Let me see if I can get some clarity:
If I define a constant:
constant pi = 3.14
what happens when I try to rebind it later?
# later
pi = 3.1415

The Windows registry isn't a class. The Windows registry doesn't prevent
you from changing values or deleting keys.
If the keys and values in the registry were constant, then you couldn't
control the behaviour of Windows, or install new applications, drivers,
printers, hardware, etc. So I don't think the registry is a good
example.
