I've made a tiny start at the 'builtin::' idea, at: https://github.com/leonerd/perl5/tree/boolean-builtins Just sufficient enough to provide the missing functions required for the "boolean" feature; RFC 0008: https://github.com/Perl/RFCs/blob/master/rfcs/rfc0008.md It still needs, for a minimal attempt that we can merge into core: * Docs * An 'import' sub If anyone wants to help writing those - especially the docs - your assistance would be most welcome ;) Also ideally before 5.36 release, I'd like to build a mechanism to use the callchecker, to replace calls to these functions with some more efficient ops. There's no point making an ENTERSUB for builtin::true, for example, when that can just be an OP_CONST of PL_sv_yes directly. Such a mechanism should be quite useful for most of the builtin funcs. -- Paul "LeoNerd" Evans leonerd@leonerd.org.uk | https://metacpan.org/author/PEVANS http://www.leonerd.org.uk/ | https://www.tindie.com/stores/leonerd/Thread Next
