Comment(by anonymous):

 I believe this is not a bug. not a boost bug anyway.

 did you use GCC for this?
 up until GCC 4.4 it had a bug that caused ADL lookups in namespaces that
 are only referred to by template argument.

 just because the "fusion" namespace appears in a template argument should
 not cause an ADL lookup in that namespace, if none of the arguments are in
 that namespace.

 fixed in GCC 4.5 and other compilers.
