m4_dnl
m4_dnl First we define a simple 'cv_qual' macro which takes a number, either
m4_dnl   0, 1, 2, or 3, and determines cv-qualification.
m4_dnl
m4_define(`cv_qual',
`m4_ifelse($1, 0, `',
`m4_ifelse($1, 1, `const ',
`m4_ifelse($1, 2, `volatile ',
`m4_ifelse($1, 3, `const volatile ',
`m4_errprint(m4___file__:m4___line__: `Boost m4 script: cv-determiner: Not 0, 1, 2, or 3 (was '$1`)')'
)')')')')m4_dnl
m4_dnl
m4_dnl Next we go through the actual loop.  For each number of arguments from
m4_dnl   1 to NumberOfArguments, we create a template function that takes that
m4_dnl   many template arguments, and also generate all cv-qualified permutations
m4_dnl   of that function.
m4_dnl
BOOST_M4_FOR(N, 1, NumberOfArguments + 1,
`BOOST_M4_FOR(cv, 0, m4_eval(4 ** N),
  `template <BOOST_M4_FOR(i, 0, N, `typename T`'i', `, ')>
element_type * construct(BOOST_M4_FOR(i, 0, N,
    `cv_qual(m4_eval((cv >> (i * 2)) % 4))T`'i & a`'i', `, '))
{
  element_type * const ret = (malloc)();
  if (ret == 0)
    return ret;
  try { new (ret) element_type(BOOST_M4_FOR(i, 0, N, `a`'i', `, ')); }
  catch (...) { (free)(ret); throw; }
  return ret;
}
