boost::result_of not honoring F::result

Reported by: Christopher Schmidt Owned by: danmarsden
Milestone: Boost 1.40.0 Component: fusion
Version: Boost Development Trunk Severity: Problem
Keywords: c++0x Cc:

Description

boost::result_of used with compilers with decltype support seems to be inconsistent with the documentation. The decltype implementation does not honor the result metafunction at all, which yields to problems when using boost::result_of on pure metafunction classes, such as being done in Boost.Fusion (e.g. see the trunk issues on the zip_view testcases on gcc-4.4.0_gnu++0x).

The behavior of boost::result_of is correct according to the standard. Fusion is using it incorrectly.
