This is novel. ;-)

There are a zillion template languages. I've written several. :)
Template-Toolkit is quite popular. However, depending on syntax, it
may be faster to do:
$template =~ s/<(\$\w+)>/$1/eeg;
(Yes, two e's) Where the variables are loaded in variables by name,
e.g. $first_name, $last_name, etc. Alternatively, you could:
$template =~ s/<\$(\w+)>/$some_hash->{$1}/g;
where $some_hash is:
my($some_hash) = {
first_name => "Rob",
last_naem => "Nagler",
};
or $some_hash could be "tied" to a dbm file or you could
