mruby 4.0 widened ENTER's operand to 24 bits and put MRB_ASPEC_NOBLOCK in the new top bit, which the compiler sets for def m(&nil). vm.c raises ArgumentError "no block accepted" when a block arrives anyway.

examples/hi.mrb and examples/simple.mrb are both RITE0300, so rite::load refuses them now. Nothing but the docs read them, their names do not match their contents, and their sources are not in the tree. The doc example and the README read a path instead of bundling a blob, and the IREP example drops no_run so cargo test --doc runs it.
