Instead, if you don't always want to compute both outputs, but still want
to write the shared computations only once, you can refactor the code to
pull out the shared computations into another function (that is "lower
level" in the sense that users won't normally call it directly):
function some_stuff(...)
...do some stuff, get x, y, and z....
....use x, y, and z to compute output1....
return output1,x,y,z
end
function compute_output1(...)
return some_stuff(...)[1]
end
function compute_two_outputs(...)
output1,x,y,z = some_stuff(...)
....use output1, x, y, and z to compute output2....
return output1, output2
end
