This class represents a derivative of an <b><code>MDObject</code></b> which is a C++ object
 and an additional bracketed prefix.  These were seen in a dumpbin of a source program that
 I created, but undname does not support the symbol.  I do not know what to call this type
 of object, so the name is descriptive for now.  Some bracketed prefix have been
 <b><code>[T2M]</code></b> and <b><code>[MEP]</code></b>, which we have gleaned by searching
 the Internet to possibly mean "Transition to Managed (code)" and "Managed Entry Point."
