The BOOST_PP_REPEAT_FROM_TO_D macro represents a fast horizontal repetition construct. It reenters BOOST_PP_WHILE with maximum efficiency.

#### Usage

BOOST_PP_REPEAT_FROM_TO_D(d, first, last, macro, data)

#### Arguments

d
  The next available BOOST_PP_WHILE iteration.
first
  The lower bound of the repetition. Valid values range from 0 to BOOST_PP_LIMIT_MAG.
last
  The upper bound of the repetition. Valid values range from 0 to BOOST_PP_LIMIT_MAG.
macro
  A ternary operation of the form macro(z, n, data). This macro is expanded by BOOST_PP_REPEAT 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, first, data) macro(z, first + 1, data) ... macro(z, last - 1, data)
The number of repetitions (i.e. last - first) must not exceed BOOST_PP_LIMIT_REPEAT.
The z value that is passed to macro represents the next available repetition dimension. Other macros that have _Z suffix variants internally use BOOST_PP_REPEAT--for example, BOOST_PP_ENUM_PARAMS and BOOST_PP_ENUM_PARAMS_Z. Using these _Z versions is not strictly necessary, but passing the z value (that is passed to macro) to these macros allows them to reenter BOOST_PP_REPEAT with maximum efficiency.
To directly use this z value, rather than simply passing it to another macro, see BOOST_PP_REPEAT_FROM_TO_D_z.
