	// Many of the methods of Microsoft.VisualBasic.dll take
	// default argument values. The whole of Mono's
	// Microsoft.VisualBasic.dll is implemented in C# and C#
	// provides no standard constructs that lets a method specify
	// default argument values and set appropriate metadata on a
	// method parameter.

	// This internal attribute:
	// Microsoft.VisualBasic.CompilerServices.__DefaultArgumentValueAttribute
	// is used to associate a default argument value with a method
	// parameter. 

	// The compiled Microsoft.VisualBasic.dll assembly is then
	// post-processed through a "disassemble-fixup-assemble cycle"
	// which strips off the "__DefaultArgumentValue" custom
	// attribute from the method parameter and replaces it with
	// the suitable CIL parameter flags and constants.
