+ *				storage is part of the call frame.
+ * VAR_DEAD_HASH		1 means that this var's entry in the hashtable

+ * VAR_ARRAY_ELEMENT -		1 means that this variable is an array
+ *				element, so it is not legal for it to be an
+ *				array itself (the VAR_ARRAY flag had better
+ *				not be set).
+ * VAR_NAMESPACE_VAR -		1 means that this variable was declared as a
+ *				namespace variable. This flag ensures it
+ *				persists until its namespace is destroyed or
+ *				until the variable is unset; it will persist
+ *				even if it has not been initialized and is
+ *				marked undefined. The variable's refCount is

+ * VAR_TRACE_ACTIVE -		1 means that trace processing is currently

+ *				read or write accesses should not cause trace
+ *				procedures to be called and the variable can't
+ *				be deleted.
+ * VAR_SEARCH_ACTIVE
+ *
+ * The following additional flags are used with the CompiledLocal type defined
+ * below:
+ *
+ * VAR_ARGUMENT -		1 means that this variable holds a procedure

+ * VAR_TEMPORARY -		1 if the local variable is an anonymous
+ *				temporary variable. Temporaries have a NULL
+ *				name.
+ * VAR_RESOLVED -		1 if name resolution has been done for this
+ *				variable.
+ * VAR_IS_ARGS			1 if this variable is the last argument and is
+ *				named "args".
