Old ticket, esp. given the nqp-rx reference. The behavior in rakudo now matches 
the behavior 
in STD:

08:54 < [Coke]> rakudo: "foo" ~~ / $<foo><bar> = [ foo ] /; say $<foo><bar>
                #76266
08:54 <+camelia> rakudo b2072f: OUTPUT«===SORRY!===␤Unrecognized regex
                 metacharacter = (must be quoted to match literally)␤at
                 /tmp/e83OQ1Z2oA:1␤------> "foo" ~~ / $<foo><bar> ⏏= [ foo ] /;
                 say $<foo><bar> #76266␤Unable to parse regex; couldn't find
                 final '/'␤at /tmp/…
08:55 < [Coke]> std: "foo" ~~ / $<foo><bar> = [ foo ] /; say $<foo><bar> #76266
08:55 <+camelia> std d4cc5ab: OUTPUT«===SORRY!===␤Unrecognized regex
                 metacharacter = (must be quoted to match literally) at
                 /tmp/WaZTcGIrM8 line 1:␤------> "foo" ~~ / $<foo><bar> =⏏ [
                 foo ] /; say $<foo><bar> #76266␤Unable to parse regex;
                 couldn't find final '/' at /…

Ticket is closable with tests.
