Hello together,

for advanced processing of capturing groups in regular expression, I'd like
to propose to expose their offsets within the results of executing an
expression on a string.

The complete proposal can be found at

I'd like it to be added to the Stage 0 proposals
<> and
I'm asking for feedback and a champion to help me bring it into shape and
get it into the standard.

Thank you in advance,
