Thanks for the light you shed on the "namespace" issue, and for the additional
info and code example. I'll be studying more about the info you shared. Also,
I tried out your code example, to get firsthand experience with it.
Cheers,

Oh, I see. You translated from Hermes into Java, and Java doesn't have

What does the programmer have to do to implement this semantic in the
sort of language you're talking about? Surely something somewhere along

Well, yes. That's the point of static typing.
it doesn't.
int x = (int) 20.5;
There's no point at which bits from the floating point representation
appear in the variable x.
int * x = (int *) 0;
There's nothing that indicates all the bits of "x" are zero, and indeed
