| Subject: [boost] Output Formatters
| There has been recent discussion about the similarity between serialization
| and display. In response to this I have implemented an experimental data
| input mechanism for text-based systems in my library:

| boost-sandbox/libs/example/serialize.cpp

Sorry if I am half blind/ inefficient with CVS, but I could not find this ^^^^^

| I have several questions:
| [1] Is there a demand for input support of complex/sequential data types
| from a stream?

Yes, IMO.

| [2] What are peoples views on my implementation? Should I continue?


| [3] Is there a need for better exception/error information from a failed
| input operation -- incompatible data types; size of list not supplied; data
| type to small to fit the data; etc.?


| [4] When implementing an input operation on a stream, it is advised/required
| you should not modify the object passed to it unless the operation succeeds.
| My feeling on this is that it would lead to inefficiencies (i.e. excessive
| copying). I want to construct the object on the fly, leaving a partially
| constructed object on failure, to improve efficiency. I will strongly
| document this deviated behaviour, but what do other people feel about this?

Probably worth a compromise.
| Documentation will be provided if there is interest in this addition.
| Aside from this addiion, do people feel that my library is ready for review.

Looks promising to me, but I can see that a 'merger' with serialization may
prove attractive longer-term.
