Tuple function calls with non tuple left side (from MathCore)

[krsta]

Modelica standard library uses first example below(from 3.0 spec)

Function "eigen" to compute eigenvalues and optionally eigenvectors may be called in the following ways:

ev = eigen(A); // calculate eigenvalues
x = isStable(eigen(A)); // used in an expression
(ev, vr) = eigen(A) // calculate eigenvectors
(ev,vr,vl) = eigen(A) // and also left eigenvectors
(ev,,vl) = eigen(A) // no right eigenvectors

This is not implemented in openmodelica.

This was fixed in r5900, with testcase mofiles/TupleSingleAssign.mo
