You discovered an Interchange feature quite by accident, what you're
doing is essentially the same thing as this:
<http://www.icdevgroup.org/interchange-doc-5.2.0/frames/icprogrammer_7.html>
If you want a sub to be localized to the usertag then you can do
something like this instead:
my $apply_discount = sub {
...some more code...
}
...
# Call the sub
$apply_discount->();
