Cool.  I wonder how long it will take the distros to pick that up
though.  Sure, I could build my own packages, but the distro/arch matrix
here makes that somewhat prohibitive.

I suppose by that same token trying to play with FDs so that:

foo() {

    echo "this is a message the user should see on stdout"

    echo "this is the function return value"

echo "bar==$bar"


$ foo.sh 2>/dev/null
this is a message the user should see on stdout
bar==this is the function return value

Is equally difficult?  Or can I more easily play with FD duplication and
redirection to achieve that, even if it means adding a ">&word" at the
end of things I want on the real stdout?
