Juerd complained about unreadable templating code here Juerd then supplied a snippet that was nice, but non-nestable and non-assignable. Here is an attempt to maintain the niceness of the original snippet, and also make it reusable and assignable.
=for comment
Here we retain Juerd's nice readable curly-brace syntax, and we also
allow for reusable code (by assigning to global output string)
allow for paramaterized tags (by using array ref with prm_table)
allow for multiple-nested tags of any nesting-depth
