Patch that implements multiple visitation in Boost.Variant

Reported by: Antony Polukhin Owned by: ebf
Milestone: To Be Determined Component: variant
Version: Boost Development Trunk Severity: Problem
Keywords: Cc:

Description

Boost.Variant has boost::apply_visitor for unary and binary visitation. That's good, but some users need more...

File in attachment provides an ability to make ternary and quad visitation by default. And it is capable of generating boost::apply_visitor for even more amount of parameters, if BOOST_VARAINT_MAX_MULTIVIZITOR_PARAMS defined to value bigger than 4.
