How do I use ~ with Regex syntax?

[ToddAndMargo via perl6-users]

Hi All,

Yes, I know to just put the variable inside the quote, but
I'd still like to know how to do it outside the quote;


$NewPage ) ~~ s/ .*? "Full Change Log for Version " ~ $YearRev //;

------> Full Change Log for Version " ~ $YearRev⏏ //;
Couldn't find terminator /
at /home/linuxutil/./GetUpdates.pl6:4960
------>  s/ .*? "Full Change Log for Version " ~⏏ $YearRev //;
    expecting any of:
        /


Many thanks,
