The deferred interpolation of scalars in a regex can still be depended on if the deference of all the various interpolations involved can be synched up properly.

(However, I share the suspicions of others about this approach to what seems like a templating problem.) 

>perl -wMstrict -le
"my $rx = qr{ foo/bar }xms;
 print $rx;
 ;;
 my $str = 'xx foo/bar yy';
 eval qq{
   print q{match}           if \$str =~ \$rx;
   my \$ry = q{$rx};
   print qq{captured '\$1'} if \$str =~ m/(\$ry)/;
   };
 $@ and die qq{eval err: $@};
"
(?^msx: foo/bar )
match
captured 'foo/bar'

Update: Slightly altered example code to more closely match my previous post.
