'handle'? I think it shows up as '6.2.13' simply because it was uploaded 
with the filename Perl6-Pugs-6.2.13.tar.gz

As you point out, the code has the kind of $VERSION number we've been 
suggesting in this thread:

Yes, this was already like one of my suggestions (1.0502_01), but I 
brought up the concern that 1.05 might be < 1.4.

So then we have a question: do we try and fumble a 1.4 compatible number 
by using 1.60_10, or do we have a clean break, remove 1.4 from CPAN if 
it causes problems, and go for the 'proper' 1.006000 (1.6.0) with no 
room for RC numbering, or 1.006000010 ( - the first final 
release following some 1.006000_001 ( == rc1) RCs?

I don't think it would be a hassle; on the contrary it would be very 
useful to know the CPAN distribution actually works. I'm very happy with 
the idea that a release candidate gets fully tested...
