Timo, perl6-users,

I don't want to print out the WHOLE text resulting from the match (in my
case a long file,) but just the /replacement/ string.

I'm sticking with syntax such as (which is also - for me - readable)

$layn ~~ s:g
    / (\W) [[RMA\.]? OpenNURBS\.]? I? On (<[2..4]>) dPoint
}/; say "$r $n $/" if $/;

[note that $r only appears once in the rule but both defines and effects
the replacement,  and that    {""if++$n;   counts the replacements due to
:g   ].

Still it would be more straightforward to have something like
     $layn ~~ s:g/ (\W) [[RMA\.]? OpenNURBS\.]? I? On (<[2..4]>) dPoint
and have a more perl6-built-in way of getting hold of the /replacement/ and
the count.
