It'd have to be spelled *c = &b, or c.value = &b or c.setvalue(&b), or
something like that, to mean the latter.

Er, how would that make them not first class? Lots of operations need to
be spelled differently, that's why we have so many operators, attribute
lookup syntax, etc. "Assign to the variable object that is in this
variable" would be a distinct operation from "Assign to this variable",
just like "add one to this value" or "call this function" etc.
