	/// <summary>  The function of this class is to proxy for the calling parameter to the VM.
	/// *
	/// This class is designed to be used in conjunction with the VMContext class
	/// which knows how to get and set values via it, rather than a simple get()
	/// or put() from a hashtable-like object.
	/// *
	/// There is probably a lot of undocumented subtlty here, so step lightly.
	/// *
	/// We rely on the observation that an instance of this object has a constant
	/// state throughout its lifetime as it's bound to the use-instance of a VM.
	/// In other words, it's created by the VelocimacroProxy class, to represent
	/// one of the arguments to a VM in a specific template.  Since the template
	/// is fixed (it's a file...), we don't have to worry that the args to the VM
	/// will change.  Yes, the VM will be called in other templates, or in other 
	/// places on the same template, bit those are different use-instances.
	/// *
	/// These arguments can be, in the lingo of
	/// the parser, one of :
	/// <ul>
	/// <li> Reference() : anything that starts with '$'
	/// <li> StringLiteral() : something like "$foo" or "hello geir"
	/// <li> NumberLiteral() : 1, 2 etc
	/// <li> IntegerRange() : [ 1..2] or [$foo .. $bar]
	/// <li> ObjectArray() : [ "a", "b", "c"]
	/// <li> True() : true
	/// <li> False() : false
	/// <li>Word() : not likely - this is simply allowed by the parser so we can have
	/// syntactical sugar like #foreach($a in $b)  where 'in' is the Word  
	/// </ul>
	/// Now, Reference(), StringLit, NumberLit, IntRange, ObjArr are all dynamic things, so 
	/// their value is gotten with the use of a context.  The others are constants.  The trick
	/// we rely on is that the context rather than this class really represents the 
	/// state of the argument. We are simply proxying for the thing, returning the proper value 
	/// when asked, and storing the proper value in the appropriate context when asked.
	/// *
	/// So, the hope here, so an instance of this can be shared across threads, is to
	/// keep any dynamic stuff out of it, relying on trick of having the appropriate 
	/// context handed to us, and when a constant argument, letting VMContext punch that 
	/// into a local context.
