Template::Toolkit - accessing hashes when keys starts with underscore?

jaa has asked for the wisdom of the Perl Monks concerning the following question:

Dear Monks,

I am a TT newbie, so apologies in advance for what may be obvious to you!

This TT snippet works:

 [% 
    # perl - $row->{action} = [qw( a b c )];
    dumper.dump( row.action )
 %]
[download]

But this fails, I assume because the underscore is the TT op for concatination.

 [% 
    # perl - $row->{_action} = [qw( a b c )];
    dumper.dump( row._action )
 %]
[download]

How do I access values in TT from a hash where the hashkey starts with underscore?

Many thanks,

Jeff

The docs say: Any key in a hash which starts with a '_' or '.' character will be considered private and cannot be evaluated or updated from within a template. update: but You can disable this feature by setting the $Template::Stash::PRIVATE package variable to a false value. `$Template::Stash::PRIVATE = undef; # now you can thing._private`	[reply] [d/l]

arghh! found this link: http://www.stonehenge.com/merlyn/LinuxMag/col61.html which says Keys in hashes that start with underscore or dot are considered private, and may not be accessed by any means. So looks like I cannot marry the existing data structures into TT without post-processing... sigh.	[reply]
