Hi,
[using gcc-4.7.2 on Red Hat Linux 6.2]
i have problems to avoid copy construction for fusion::map elements. See test 
program below. It shall pass a fusion::map as context along a call hierarchy 
with option to add elements (and in future maybe modify elements - if possible).
Either i use
#define USE_RVALUE_REF 0
and have copy-constructions (strange especially for the at_key lookup for Data 
in exec2()!)
Or i use
#define USE_RVALUE_REF 1
and get a compilation problem for code to "retrieve Data..."
Can you pls. help me?
I don't think the fusion containers support
rvalue reference members right now.
