Vicente, Gordon,
Thank you for the pointer, I had a quick look and indeed it seems to solve the specialization problem I was facing. Should we cancel/postpone this review and review Vicente's and mine together or something of that sort? If Vicente's is better as a starting point, it's fine by me. I am happy either way a s long as things are moving.
Vicente,
I had a quick look and your proposal. Conceptually it seems to be an extension of lexical_cast philosophy on to type-to-type conversions. It does not seem to provide any of the functionality that I (as a user) care about, i.e., fallback value, throwing/non-throwing, formatting, locales, etc. Given convert_to actually returns a Target value, I suspect, formatting, locales, etc. are simply not possible as I believe we have to have an intermediary object (converter) to apply additional formatting, etc. Am I correct in my reading?
If so, then you and I are trying to address totally unrelated issues. I needed 'convert' as lexical_cast not not doing what I needed it to do. I do not think I immediately have a need for type-to-type extension of lexical_cast.
I have a problem with less and greater symbols, please open the attached file that corresponds to my preceding mail (I've some configuration issues). Sorry for the inconvenience. Vicente
