[Boost-users] [bind][factory] Nested binds with functional/factory

Dear all,

I'm trying to use boost::bind in combination with
boost/functional/factory.hpp (and value_factory)

this works fine, 

boost::bind( boost::factory<T*>(), arg1, _1 )

with arg1 not being an lvalue (e.g., 2.0).

however, with nested binds it is not accepted, 

boost::bind( boost::factory<T*>(), boost::bind( f, _1 ), _2 )

the compiler complains that it needs an lvalue for the nested bind. Is this
desired behaviour? Is there some trick around this?

Many thanks,
Kind regards,
