capture through regex variable

[Theo van den Heuvel]

Hi all,

I am trying to change a regex programmatically. For that I insert a 
variable in another regex. However, the match object appears to have 
lost the capture of the inner regex. In a code example:

=========
my Match $match;

my $top = rx/ \( $<core> = [ \w* ] \) /;

given "(abc)" {
  $match = m/^ <$top>/;
}

if $match {
  say "core is { ~$<core> }";
}

=========

Using the latest rakudo release (2016.01.1), I find that the matching 
process works but the capture gets lost. Any ideas?

Thanks,
