The BOOST_PP_ENUM_PARAMS_Z macro generates a comma-separated list of parameters. It reenters BOOST_PP_REPEAT with maximum efficiency.

#### Usage

BOOST_PP_ENUM_PARAMS_Z(z, count, param)

#### Arguments

z
  The next available BOOST_PP_REPEAT dimension.
count
  The number of parameters to generate. Valid values range from 0 to BOOST_PP_LIMIT_REPEAT.
param
  The text of the parameter. BOOST_PP_ENUM_PARAMS_Z concatenates numbers ranging from 0 to count - 1 to generate parameters.

#### Remarks

This macro expands to the comma-separated sequence:
param ## 0, param ## 1, ... param ## count - 1

- BOOST_PP_LIMIT_REPEAT

#### Requirements

Header: <boost/preprocessor/repetition/enum_params.hpp>

#### Sample Code

    #include <boost/preprocessor/arithmetic/inc.hpp>
    #include <boost/preprocessor/repetition/enum_params.hpp>
    #include <boost/preprocessor/repetition/repeat.hpp>

    #define MACRO(z, n, _) \
       template< \
          BOOST_PP_ENUM_PARAMS_Z(z, BOOST_PP_INC(n), class T) \
       > class X ## n { \
          /* ... */ \
       }; \
       /**/

    BOOST_PP_REPEAT(2, MACRO, nil)
    /*
       expands to...
       template<class T0> class X0 { };
       template<class T0, class T1> class X1 { };
