Now, that's fine enough, but for simplicity (and for wireshark), I'd
like to be able to have Binary fall back on an instance based on
Show/Read for any type that lacks any other Binary instance..
Well, I understand why this would be somewhere between extremely hard
and impossible in haskell '98, but I'm not entirely up on all the
extensions, so I thought I'd ask - given every extension implemented
in ghc 6.10.1, is there any reasonable way to do this?
I'm not sure what you mean by falling back on Show/Read instances,
but this seems like a typical generic programming problem. Recent
releases include the EMGM and SYB libraries for generic programming.
