I have a Perl 5 module called Every which provides, simply, every(5); # true on invocation 5, 10, etc. every(seconds => 5); # true at 5, 10, etc. seconds
It's really nice in endless loops, logging, etc. I'd like to translate it to Perl 6 (using Rakudo specifically). Its current implementation requires Devel::Opcode because it needs to know what location is getting called again and again. Generally for Perl 6, is there a simple way to make Every obsolete by using built-ins? I'd love that but haven't seen anything in the language that would help. I want to avoid closures, they are expensive (the current implementation uses one hash key per location). Maybe I could use a continuation (I don't know the syntax for that)? Specifically for Rakudo, if I have to implement it, can I avoid Devel::Opcode? Are continuations expensive? Thanks for any help Ted
