In TT '>=' *is* a text comparison operator!

Well if you look at it, that's obviously an expression 'the gold field 
from HASH minus 1.  The syntax doesn't 'work' in Perl either. Why would 
you expect it to 'work' here?  You have two solutions, change the keys 
or assign them to variables. Both can be automated, so why worry?

It seems to me that a quiet weekend with the Badger book would be 
beneficial.

Why not
[% SET foo = 'gold-1'; IF GLOBAL.PRODUCT_DATE.$foo > current_date %]

So (untested):

[% PERL %] $stash->set(foo =>
$self->{GLOBAL}->{PRODUCT_DATE}->{'gold-1'} gt $current_date
) [% END ; IF foo %]

which again is just an automatic template transformation away.

So why not use Perl?  You must believe TT is better for your application 
instead of your existing system, to make it worth doing the transition.
