Detailed Description

AST Node representing Variable Scope.

Every VariableDef has a scope within which it is visible and alive. For example, a local variable's scope is the compound block sorrounding the variable declaration, or a for() variable's scope is the statement's compound block. A continuation is a sequence of named closures, each of which is represented as a named variable that exists for the lifetime of the continuation.
