Given that variadic macros are supported for just about all compilers 
now, the Boost PP array is largely obsolete as the Boost PP tuple has 
all the functionality which an array has except for the fact that a 
tuple can never hold 0 elements while an array can. Therefore I am 
trying to phase out the use of Boost PP arrays in favor of Boost PP tuples.

If you change your functionality to work with tuples instead when 
variadic macros are being used, and create a PR for it against the Boost 
PP 'develop' branch, I would be happy to look at it and merge it into 
Boost PP.
