Have you tried *_1 ?

I think that works with boost::lambda::bind and boost::lambda::_1 (also, presumably, the corresponding constructs in Phoenix) but not with plain boost::bind.

Indeed I tried that - getting invalid indirection error.

Some time ago I offered a patch to add arithmetical operator support to Boost.Bind and was answered : Use Lambda or Phoenix. If you want to tweak Boost.Bind, which I would not encourage, maybe this could help : http://boost.2283326.n4.nabble.com/Bind-Function-arithmetic-sample-impl-insi... As said, it is for arithmetical operators but might be adapted to your need. Regards, Ivan
