The BOOST_PP_TUPLE_POP_BACK_Z macro pops an element from the end of an tuple.  It reenters BOOST_PP_REPEAT with maximum efficiency.

Usage

BOOST_PP_TUPLE_POP_BACK_Z(z, tuple) (v)

Arguments

z
The next available BOOST_PP_REPEAT dimension.
tuple
The tuple to pop an element from.

Remarks

This macro returns tuple after removing the last element.  If tuple has only a single element, it remains unchanged since a tuple must have at least one element.
