Template reserved words

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

Hi Monks
Hopfully this is an easy one but I can't figure it.
How would one go about displaying a hash in a Tempalte file when the hash key is a reserved word in Template?
e.g

[% FOR line IN xml %] [% line.size.value %] [% END %]

It seems both "size" and "value" are reserved words in Template. I did try "ANYCASE => 0" but it doesn't do what I need. Anyone?

    You can get around the unfortunate choice of keys by using Variable Interpolation:
    [% FOR line IN xml %] [% size_key = 'size'; value_key = 'value'; line.$size_key.$value_key %] [% END %]

    This assumes you are using Template::Toolkit, of course.
