 * type constructors, and other statements beyond the type-checking code within the TCB itself.
 * Through method calls on `Environment`, the TCB generator can request `ts.Expression`s which
 * reference declarations in the `Environment` for these artifacts`.
 *
 * `Environment` can be used in a standalone fashion, or can be extended to support more specialized
