    Add tests for calling closures
    
    Add checks for correct handling of closure calls.
    Regress.test_closure_one_arg() is working fine and should continue to do so.
    Regress.test_closure_variant() is known to not work yet, so mark this as EXFAIL
    for now. (See https://bugzilla.gnome.org/show_bug.cgi?id=656554)
