Class: Frame

lib/core/expression/evaluator~Frame(parent, bindings)

A chain of name bindings.

Arrow-function parameters and nothing else live here; everything else resolves against the scope the caller supplied. Keeping the two separate is what stops a lambda parameter from silently writing to component state.
