Now, there are two local binders: let x = ... use x = ... The 'let' binder will create a local definition, type-check it, and assign a name to it. When compiled, it will create 'dup' nodes. The 'use' binder is just an alias. It will not bind a new variable, and, when compiled, will create inline copies. Also, for type-checking, it allows creating aliases that are definitionaly equal for the checker.
