Re: [Boost-users] [preprocessor] one comma too many

However, I would like to replace "T" with the following instead:

std::pair<T, T>

ie: I want to write something to the effect of:

BOOST_PP_ENUM_PARAMS(n, std::pair<T, T> r)

Of course, BOOST_PP_ENUM_PARAMS now sees one too many arguments, and errors. Any ideas on how to achieve this would be most appreciated.

With thanks in advance,

Hi, You must use a typedef to hide that comma : typedef std::pair<T, T> pairTT_t; BOOST_PP_ENUM_PARAM(n, pairTT_t r) -- Maxime
