The Command pattern looks like transactional programming which is used in SystemC and similar systems-level programming languages. The idea is that transactions or commands have properties like atomicity and so forth to deal correctly with concurrent behaviors. Language support may be the deciding factor for young students, but conceptually the more interesting engineering debate would be which paradigm is better for a given purpose, coroutines or commands/transactions assuming the programming language can cleanly express both.
