slot Slot!T slot(string name): Lift a placeholder - slot for concrete value to be filled in at a later stage
slot Slot!T slot(string name, Slot!T value): Register existing slot at this _stage_ with name name
slot Slot!T slot(Slot!T value): Register existing slot at this _stage_ with original name
eval auto eval(Lift!T value): Try to evaluate (lower) lifted value using this stage
partial auto partial(U value): Do partial evaluation for lifted value, this folds all known-constant sub-tries and optimizes expressions
register void register(Slot!T slot): Undocumented in source. Be warned that the author may not have intended to support it.
register void register(string name, Box box): This is an implementation hook - register must save name,typeinfo pair to check type matching later
opIndexAssign Box opIndexAssign(Box value, string name): This is an implementation hook - bind must check that typeinfo matches and bind value to the lifted slot
opIndex Box opIndex(string name): Third implementation hook - lookup bound value for a given name
