I see.
How about:

inline detail::swallow_assign ignore() { return detail::swallow_assign ; }

I know this changes the syntaxis, but it doesn't introduce initialized data
in the header, so it allows the header to be precompiled.
I noticed this before, but it appears that noone cares to precompile tuples
(or other compilers allow initialize data in precompiled headers)
