Can arguments to compressed_pair be const-qualified? The documentation only lists this restriction:
Note that compressed_pair can not be instantiated if either of the template arguments is a union type, unless there is compiler support for boost::is_union, or if boost::is_union is specialised for the union type.
I believe I am getting an error from Intel C++ when an argument to compressed_pair is const. The question is whether we need a workaround in compressed_pair.hpp or a change to the html documentation.
OK, the following: boost::compressed_pair<const int, long> cp2; Gives me a compiler error with VC7.1 (it should as well, but it's not really a compressed_pair issue). Where are this: boost::compressed_pair<const int, long> cp2(0); compiles as expected. As does boost::compressed_pair<const myclass, long> cp2; as long as myclass has a user-defined default constructor. That's all exactly what I would expect, what am I missing? John.
