Hello all.
In the processing of working with mugwump's shiny new perl6 OO Set.pm.
I realized that we do not currently have a way to uniquely identify
objects in Pugs like the way we have in perl5 (object stringification).
So I asked Autrijus, and he promptly implemented a rudimentary object

As we currently have it, that is not legal syntax. "is" may only

There is syntax to define trait and properties
but is there an API?
my $b = eval '$a but true'; # setting a true property
# API to do it without an eval?
A trait setter probably does not make sense but for the
implementer because it should not be set at run time.

Currently in perl5 and pugs this prints "3\n\n\n".
Which to me looks like a mix of runtime and compile time.

Hello Rod,
I was pointed to your p6l post (<4283AAC1.6060106[at]rodadams.net>) by
Autrijus. I have already worked a bit on implementing/porting the
functionality of builtins that I want in Perl6 (by stealing from Perl5),
I can try to take over S29.

No, it's not inconsistant. Think about the simpler case split /a/,'a'
which return a list of empty strings. Now ask to keep the separators
split /(a), 'a' which will return ('', 'a', '', 'a', '', 'a', '', 'a, '',
'a'). Now look at
split /(a)/, 'aaab' which returns ('', 'a', '', 'a', '
