I expect all three to yield the same successful match.

<masak> it's just "not to spec" in an unknown way.

this is a dupe; I don't remember of what. anyways, now it errors with​:

19​:33 <diakopter> r​: my $l = 3; say "x" x 10 ~~ / x ** {$l} /

From @Mouq

In general, the output is now​:

01​:55 <Mouq> r​: my $l = 3; say "x" x 10 ~~ / x ** {$l} /
01​:55 <camelia> rakudo-parrot 79167a, rakudo-jvm 79167a, rakudo-moar 79167a​: OUTPUT«===SORRY!=== Error while compiling
  /tmp/tmpfile␤Block case of ** quantifier not yet implemented␤at /tmp/tmpfile​:1␤------> my $l = 3; say "x"
  x 10 ~~ / x ** ⏏{$l} /␤ …»

Although x ** $l gives​:

01​:51 <Mouq> r​: my $l = 4; say "foooo" ~~ /^ f o ** $l $/
01​:52 <camelia> rakudo-parrot 79167a, rakudo-jvm 79167a, rakudo-moar 79167a​: OUTPUT«===SORRY!=== Error while compiling

Which is still LTA.
