Actually, to clarify, I consider the 0dNN syntax quite important too, and so the offered grant of up to $100 is to add *both* 0oNN plus 0dNN syntaxes, so then the 4 [bodx] are supported, like Perl 6 does. A rationale for having 0d also is that users can then write literals with leading zeros in all 4 radixes and there would be no confusion of the meaning versus 0NN both now and after the possible removal of 0NN meaning octal later. And meanwhile any 0NN in code can then give a warning to suggest either 0o or 0d depending what is meant. -- Darren Duncan Darren Duncan wrote: > Hello, > > P.S.
