I would have said this was a compiler bug. But on the other hand there is even 
a special error message about '>>' needing to be '> >' within a nested 
template argument. Yuck, how arbitrary! So I'll fix the bug by adding a 
suitable space for types ending in '>>'. I haven't switched to subversion 
yet, so it might be a day or two.
