Sorry for the delayed response.
The question was:
Given the use of perl-style back-references ( like "${1}" ) - would it not
make sense to use the same perl syntax to provide well-defined targets for
those back-references?
E.g. "my-special-(<regex-thing>)-(<regex-thing>)-with-suffix" and then
there is no ambiguity as to what ${1} and ${2} point at?
Perl regex rules are IMHO very clean and clever, and avoid ambiguity very
nicely.
(Also historical shout-out to Henry Spencer, whose regex mods served as the
source for perl's.)
Things inside parentheses are the target of back-refs.
In Perl, there is no need to escape the parentheses within regexes.
