Well, "bind" is not that difficult -- Algol 68 surely allows you to.
"rebind" is different, and the exmaple you have seems to imply
rebinding, not binding. Even in this case you need not go far -- Lisp
systems are what you want to look at.

Or maybe you should explain what you mean by "bind", because I have the
suspicion that you may actually want to "redeclare", i.e. just reuse an
identifier symbol. Well, macro languages provide the needed example
(#undef, #define).
