I've been following this discussion because I have also quickly hit the
point where I need to interpolate other hiera values.
Would it be possible to have % and ^ alias to a more descriptive
nomenclature?
Something like % == scope and ^ == hiera? With the previous example:
scope{potto01_ip} and hiera{potto01_ip}
Though I miss PERL (it's a joke people), I'm a big fan of readability and
the constant sigil wrangling isn't very readable for people new to the
language and makes maintenance from the unindoctrinated more difficult.
Thanks,
Trevor
