Hi Charlie, thanks for sharing this, it looks most useful. I downloaded and ran it; the testcases run ok. I cannot figure out how to make it write MyClass.class; please forgive me my Ruby-ignorance here. I removed the things I though to be for the testcase only, and have it execute outside of a method. It executes ok, but Erik Meijer would be very happy: there are no side-effects. That I know of.
best regards and thanks in advance. René.
