* fix for Mantis #34526: rely on tc_arrayconstructor_2_set instead of manually converting an array constructor to a set, this way assignment operator overloads are taken into account as well
    Note: there is still a conversion to a set if the types were determined to be incompatible, so that the error is still "set of X is incompatible to Y" instead of "array of Z is incompatible to Y"
+ added tests
