I think clearly $regml() support would require the name parameter as non-optional.
Agreed
But I still stand by my request for automatically populated variable names by design. There's no broken backward compatibility because there's nothing here that anybody already uses.
That cannot be added as it breaks scripts, previous scripts which currently use named captures in their expression would now get local variable created, or modified, the latter being more problematic. I really think the way to improve identifier like this is using the command parameter from $hfind/$findfile etc.
