in thread how to pass hash to perl template toolkit

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>
