Re: [Boost-users] [mpl] possible bug in insert<set, x>

I'm having trouble with insert<> as called on a set. Specifically, it doesn't seem to be possible to iterate over sets built with insert<>. The following code, for example, works correctly (or at least, compiles without errors):

--- typedef set m_set; typedef transform > >::type result; ---

but the following (which as I understand it should be equivalent) fails to compile:

--- typedef insert, double>::type, char>::type m_set; typedef transform > >::type result; ---

On the assumption that this is a bug, or at least a non-obvious usage error, can anyone suggest a workaround? At present I can find no way to insert an item into a set in a way that produces a usable set, and this is a major obstacle in the project I'm working on. Also, is boost or boost-users the preferred forum for these sorts of questions? boost-users seems more appropriate (since this may, after all, be an error on my part), but I've found boost to be much more responsive.
