At this point, $/ doesn't work well in subst-closures. However, the real cause 
for the RT 
ticket has been fixed:

$ perl6 -e 'my %h = B => 2; my $x = "ABC"; $x .= subst(/(<[BD]>)/, %h<B>, 
:global); say 
$x;'
A2C

$ perl6 -e 'my %h = B => 2; my $x = "ABC"; $x.=subst(/(<[BD]>)/, %h<B>, 
:global); say $x;'
A2C

Resolving ticket.
