The BOOST_PP_LIST_ENUM macro converts a list to a comma-separated list.

Usage

BOOST_PP_LIST_ENUM(list)

Arguments

list
The list to be converted.

Remarks

If list is, for example, (a, (b, (c, BOOST_PP_NIL))), this macro will produce:
a, b, c
Previously, this macro could not be used inside BOOST_PP_FOR.  There is no longer any such restriction.  It is more efficient, however, to use BOOST_PP_LIST_ENUM_R in such a situation.
