A few days ago I briefly discussed with Nicholas Clark (current perl 5.8
pumpking) about making perl5 code forward-compatible with perl6. A
quick look through the mailing list archives didn't turn up anything
obvious, and I don't recall any mechanism being presented in any of the
Apocalypses, so .

My understanding has been that perl6 will assume a program is Perl 5 unless
it sees a Perl 6 keyword such as 'module' or 'class'.

I have confused assignement and initialisation in my previous
mail. Because they are two different operations, there is no
problem they have different semantics. A6 described both
operations. It described pairs as arguments used to initialize
parameters and pairs in assignement.
