Hi,

I often use BOOST_FUSION_DEFINE_STRUCT not to generate a fusion-sequence per
se, but to get a struct with

- default initialisation for all members
- a reasonable set of constructors
- equality-check
- all above without additional code

But sometimes I would like to have additional methods in those structs, but
deriving from those or fusion-adapting them loses at least one of the nice
properties above.
After looking at the BOOST_FUSION_DEFINE_STRUCT implementation I though
about splitting the makro BOOST_FUSION_DEFINE_STRUCT_IMPL an inject my code
in-between.
Now my questions are:

- Is there anything I've overseen and might detroy some fusion-mechanism?
- Is there any chance to get macros like
BOOST_FUSION_DEFINE_STRUCT_[BEGIN|END] (and also for the other
BOOST_FUSION_DEFINE_... macros?

Tobias
