With the above example, you could show _how_ the boolean is computed. That assert would print stuff like "Assertion failed at foobar.java:123: ((5 + 6 + 8) == 18)"

Yes, but I think what's needed is more like:                 Debug.fail("Expected pathname host of '"+ p + "' to be a string, symbol, or cons");

Yes, that would be helpful. We could start with that at least, and pipe-dream about macros later. :)
