I realise that it's almost 2 years since the RFC deadline, plus we're
several apocolypses past the appropriate Camel chapters.
IIRC there are 5 different variants of m//
normal /g
scalar context: match from start continue progressive match
return true/false return true/false
list context: match from start continue progressive match
return list of captures if captures return list of
captures
else return list with all matches
this confuses me enough already. But I've just about got my head round it.
(strictly, I can only remember the left column, and that I need to check the
camel for the rest. However I then needed to write a test program because
Camel III doesn't say whether list context m//g starts from the beginning
or from pos)
This is from perl5-porters, and the wrong code was in a patch I sent:

There's only 1 version of s///, but I actually find it more confusing, since
I expect the left of a s/// to work just like a m//
So would it be possible for s/// to have the same return values as m// in
perl6?
