Tuples: draft 1

[Benjamin Kosnik]

Really quick:

>1) Need to put the tuples into a namespace. Which one?

std::tr1

>2) I declare "extern shallow_assign ignore". This needs to be actually 
>created somewhere..

Do you mean you need to link against it? What is shallow_assign ignore, exactly?

>3) Lots most tests, and also a big bunch of "not compiling" tests.
>4) While I think the header is at least passably readable, there are 
>some strange formattings, and in particular lots of very, very long lines.

Usually, negative tests are suffixed with _neg. See:

http://gcc.gnu.org/onlinedocs/libstdc++/test.html

There are several examples of how libstdc++ does negative testing in the
existing testsuite.
