As a follow-on question, why would this be implemented only now? From the very beginning, capturing the stdout of an external command involved forking a subshell, and soon (assuming funsubs remain when 5.3 is released) it won't have to. It feels like something changed to make this feasible when it hadn't been before.
I suppose it was mostly the work I did to make command substitution parsing
call the bison parser recursively instead of using the ad-hoc scheme that
had been in place for years.
Once you identify all the relevant parser state, the alternate nofork
command substitution becomes easier.
Time and motivation are always factors, of course.
