I still love the idea of ">>>variable" to direct output into a
variable without needing a subshell

I'd prefer a syntax based off:

command-list > >(command-list)
command-list < <(command-list)

But with curly braces for the no sub-shell version:

command-list > >{ command-list;}
command-list < <{ command-list;}

Which could be used to assign output of a command to a variable without a sub-shell:


mapfile -t users < <{ compgen -u; } # No sub-shell

Implementation-wise it could be a temporary file in /tmp or /dev/shm rather-than a temporary named fifo as with < <(:).
