Re: [boost] BOSOT_ENUM proposal rev 4, ENUM_VALUES extension?

Here's a request for an extension to ENUM_VALUES for you to consider.

I need to use BOOST_ENUM_VALUES with type std::size_t so I can use the  
method 'value' and use the result as an index to a vector.  I would also  
like to have an end-user readable description for the enumeration value.   
Currently I hold this in a separate class that maps enumeration values to  
descriptions.

 From what I understand, the enumeration tags have to be C++ names so no  
spaces are allowed whereas end-users don't usually like CamelCase (or  
whatever) unspaced C++ names.

Here's an example:
BOOST_ENUM_VALUES_DESCRIPTIONS(BlockType_t, std::size_t,
   (SampleIfg)(0)("Sample Interferogram")
   (SampleSpec)(1)("Sample Spectrum")
   (SamplePhase)(2)("Sample Phase")
   (RefIfg)(3)("Reference Interferogram"))

And then a method something like:
   const char* description() const;

Would anyone else find this useful?
