I liked this meditation. However, there's one thing I didn't like: the eval call in define_vocabulary, which is unneccessarry.

Let me show the way to do the same without eval. 

sub define_vocabulary {
    no strict "refs";
    my($elems, $attrs) = @_;
    for (@$elems) {
        my $name = $_;
        *{$_} = sub(&) { _elem($name, @_) };
    }
    for (@$attrs) {
        my $name = $_;
        *{$_ . "_"} = sub($) { _attr($name, @_) };
    }
}
