threaded for loop outside of list

[wbraun]

It is possible to use threaded for loop in lists, something like:

out = list( func(e,v) threaded for e in inEqns, v in inVars);

Wouldn't it be also nice to have such construct in regular loop, something like:

equation
  threaded for e in inEqns, v in inVars loop
    extraArgs = traverserStrongComponents({e}, {v}, {}, {}, extraArgs);
  end for;
