The BOOST_PP_ENUM_SHIFTED_z macro represents a reentry into the BOOST_PP_ENUM_SHIFTED repetition construct.
	
	Usage
		
			BOOST_PP_ENUM_SHIFTED_ ## z(count, macro, data)
		
	Arguments
		
			- z
- 
				The next available BOOST_PP_REPEAT dimension.
			
- count
- 
				The number of repetitious calls to macro. 
				Valid values range from 0 to BOOST_PP_LIMIT_REPEAT.
			
- macro
- 
				A ternary operation of the form macro(z, n, data). 
				This macro is expanded by BOOST_PP_ENUM_SHIFTED with the next available repetition depth,
				the current repetition number, and the auxiliary data argument. 
			
- data
- 
				Auxiliary data passed to macro.
			
Remarks
		
			This macro expands to the sequence:
			
				macro(z, 1, data), ... macro(z, count - 1, data)
			
		
			At certain times, it may be necessary to perform the concatenation with 
BOOST_PP_CAT rather than the preprocessor token-pasting operator. 
			This happens when the 
z value is a macro invocation itself. 
			It needs a delay to allow it to expand. 
			The syntax in such a scenario becomes:
			
				BOOST_PP_CAT(BOOST_PP_ENUM_SHIFTED_, z)(count, macro, data).
