[Boost-users] [preprocessor] Is there an equivalent of "delayed expansion"?

14 Apr 2013


      Is there an equivalent in boost for delaying the expansion of a macro? For  
example, I want EAT to act on TSEQ2, so I have to use trick on line 4.

#define TSEQ2 (w)(x)(y)(z)(a)(b)(c)(d 2)
#define IDENTITY(x) x
#define EAT(x)
IDENTITY(IDENTITY(EAT)TSEQ2)

Thanks,

Mostafa
