Re: Populating an undefined hashref in a sub

Thank you, anonymonk and ikegami - for pointing out that it was indeed a pass-by-ref, and can be dressed up, and perfumed with non-native syntax.

That passes the glamour and olfactory bar.

Any perl6 pointers ?

Update: Thanks, ikegami for the native syntax!

Update2: Hmm - I noticed you changed from ||= to //=
Any harm in this case with||= ? I need this to work on pre 5.10 perl.

Syntactic sugar causes cancer of the semicolon. --Alan Perlis
