To be clear, though I don't like the m_* convention, etc, there's a
bigger issue here for Java:
The convention all Java programmers have been trained with (and that
is in all books and training materials and IDEs) is simple
lower-case (leading lowercase and camel case thereafter) names for
/both /fields and properties (yes, Java *does* have properties;
JavaBeans may need improvement, but they're there).
Thus mixing Java's longstanding naming conventions with use of the "."
operator for property access is a recipe for confusion.
