/// A Guarded CTV Function
then!(guarded_by: [guard_1, ... guard_n] fn name(self, ctx) {/*Result<Box<Iterator<TransactionTemplate>>>*/} );
/// A Conditional CTV Function
then!(compile_if: [compile_if_1, ... compile_if_n] fn name(self, ctx) {/*Result<Box<Iterator<TransactionTemplate>>>*/} );
/// An Unguarded CTV Function
then!(fn name(self, ctx) {/*Result<Box<Iterator<TransactionTemplate>>>*/} );
