[e-lang] Joe-E reflection API questions

[Mark Miller]

Oops. The Reflection class I just sent also depends on Tyler's old
NoSuchMember class, which I revived without examination. I include
NoSuchMember below. I notice that it violates the common Java
convention that exception class names end with the suffix "Exception".
Another Joe-E class also violates this convention: InvalidFilename. I
suggest that we change both to follow the Java convention, even though
ref_send doesn't. I think Joe-E should stay more strictly close to
Java conventions than ref_send should.
