in thread how to pass hash to perl template toolkit

Ten years after the reply by johnnywang, I read it and found it rather useful... Prepending the variable name in add.$element.type with the dollar sign makes it work - in this piece of code and in mine. Yet according to the documentation it is ignored unless INTERPOLATE=1 is set, and the colour coding from vim-perl suggests the same.

I doubt this is that badly documented, what am I missing? Why is the '$' sign vital in there when it (seemingly) shouldn't be?

See https://metacpan.org/pod/distribution/Template-Toolkit/lib/Template/Manual/Syntax.pod#Tag-Styles

    # INTERPOLATE = 0
    <td>[% name %]</td>
    <td>[% email %]</td>

    # INTERPOLATE = 1
    <td>$name</td>
    <td>$email</td>
