I'll take a shot at it since no one else seems to want to. :-)

Named subrules have their values stored in the $/ match object under a
key of the same name. So, in this case:
$foo ~~ m/<block>/;
$/<block> will contain the matched block, and $/<block>[1] will
contain the block content (i.e. the content of the second capturing
group). The working is the same in the case of s///, so you can
probably safely use $/ within your &trigger_block and &trigger_elem.
Hypothetical variables work like this:
my $bar; # not quite sure you need to initialise it; just in case :-)
$foo ~~ m/$bar := (bar|baz)/;
Now $bar will contain either "bar" or "baz", depending on which one was matched.
Hope this is helpful. Corrections are welcome from anyone who spots
any mistakes.
