Hi Paul LeoNerd, Yes, please write the RFC. Thank you, Carl Friedberg President, Comet &Company 165 William St New York NY Office (212) 233-5470 Cell (917) 861-7819 -----Original Message----- From: Paul "LeoNerd" Evans <leonerd@leonerd.org.uk> Sent: Wednesday, August 4, 2021 10:58 AM To: Perl5 Porters <perl5-porters@perl.org> Subject: Pre-RFC: Real "boolean" SV type I propose the addition of a new SV type, of SVt_BOOL. Should I write an RFC? This type will act much like the existing "booleans" of PL_sv_no and PL_sv_yes, except its type will remain distinct, so it will be possible to distinguish "that SV is a boolean". This is a requirement for certain kinds of data serialisation - such as JSON or MsgPack - and may be useful for many other purposes too. Still to be determined: a pureperl interface on it. E.g. would this be possible: use feature 'bool'; my $yes = true; # new literal value keywords my $no = false; # use Scalar::Util 'svtype'; is( svtype($yes), "BOOL", 'true is SVt_BOOL'); Thoughts on a postcard*. *: Where "postcard" means: **PLEASE KEEP REPLIES SHORT**. This is a pre-RFC question. Replies should be limited to the question of whether I should write the RFC - not about the feature itself. -- Paul "LeoNerd" Evans leonerd@leonerd.org.uk | https://metacpan.org/author/PEVANS http://www.leonerd.org.uk/ | https://www.tindie.com/stores/leonerd/Thread Previous | Thread Next
