Guile! :-) Well, seriously, there is of course no problem adding
`identity'.  Is it in some SRFI?

The real problem is probably that boot-9 has no defined interface.
verything in it is available so we can't really know whether it is
safe to change the innards of boot-9.  Is `id' meant to be exported
from boot-9 or not?  The answer looks like "yes", since it's defined
next to `1+'.

Should we remove `id' or not?
