// This sample is taken from the C++ standard 22.214.171.124 [cpp.scope]
// Currently this test fails due to a pathologic border case, which is included
// here. Wave currently does not support expanding macros, where the
// replacement-list terminates in partial macro expansion (such as the
// definition of the macro h below). This will be fixed in a future release.

g(x+(3,4)-w) | h 5) & m(f)^m(m);
// results in:

//E f(2 * (y+1)) + f(2 * (f(2 * (z)))) % f(2 * (0)) + t(1);
//E f(2 * (2+(3,4)-0,1)) | f(2 * g( ~ 5)) & f(2 * (0,1))^m(0,1);
