$text_ref is a reference to a scalar, so to get the text itself you need
to dereference it.
It's proably easier to understand if you think of it as ${$text_ref}.
It's the same as you'd do with hash an array references.

I think that here you want:
$$text_ref =~ s/!!!ZAP_(.*?)!!!/<TMPL_$1>/g;
(as per the example in the H::T documentation)

Do you get other arguments passed into a filter? I can't say I've ever
tried, but wouldn't expect more than $text_ref. However, you want to use
$$str1 to get the actual text held in str1, $str1 is a reference to a
scalar.
I think.
