#10273: Documentation on Boost.Variant optimizations is out-of-date
-------------------------------------+------------------------
 Reporter:  David Sankel <camior@…>  |      Owner:  ebf
     Type:  Bugs                     |     Status:  new
Milestone:  To Be Determined         |  Component:  variant
  Version:  Boost 1.55.0             |   Severity:  Regression
 Keywords:                           |
-------------------------------------+------------------------
 In the 'Enabling Optimizations' section of
 http://www.boost.org/doc/libs/1_55_0/doc/html/variant/design.html it
 mentions that "On most platforms, the Type Traits templates
 has_nothrow_copy and has_nothrow_constructor by default return false for
 all class and struct types." This is no longer true.

 The documentation for those traits in the type traits library says
 'Currently (May 2011) compilers more recent than Visual C++ 8, GCC-4.3,
 Greenhills 6.0, Intel-11.0, and Codegear have the necessary compiler
 intrinsics to ensure that this trait "just works".'

 The Boost.Variant documentation should not indicate a need to explicitly
 override these functions to get the optimizations.
