Detailed Description

A bare assignment statement - rebinds an existing variable.

Example: count = count + 1

Unlike let, the name must already be declared in an enclosing scope and the new value must match the original type. Path aliases bound by as, repeat iterators, and ask-bound names are read-only and may not be reassigned.
