[boost] Passing template-ids as macro parameters

From: Terje Slettebø (tslettebo_at_[hidden])

Is there some way (using PP-lib, or whatever), to pass a template-id with
more than one parameter (thus, it contains at least one comma), to a macro?

E.g.:

#define TEST(a) test<a> t;

TEST(std::pair<char,int>) // Won't work

Maybe some sort of variation of BOOST_PP_IDENTITY:

#define BOOST_PP_IDENTITY1(a) a
#define BOOST_PP_IDENTITY2(a,b) a,b
#define BOOST_PP_IDENTITY3(a,b,c) a,b,c

etc.

TEST(BOOST_PP_IDENTITY2(std::pair<char,int>)) // Now ok
