It's a bug somewhere, yes. I suspect that PGE is tying to
the scalar variable itself where it needs to be tying to the
value.

$/.text and ~$/ are different: $/.text always returns the
matched text, while ~$/ returns the stringification of the
result object (which could be different from the matched text
if C<make> was used inside of the regex).
"81" ~~ / (\d+) { make $0.sqrt } /;
say ~$/; # "9\n"
say $/.text; # "81\n"
(C<make> and closures in regexes are not implemented in Rakudo yet.)
