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

std::pair

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

BOOST_PP_ENUM_PARAMS(n, std::pair 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 pairTT_t; BOOST_PP_ENUM_PARAM(n, pairTT_t r)

Thank you Maxime for pointing out the obvious, I should have known better. Cheers, -- Manfred
