It looks to me like match doesn't work nicely with #:super structs.  For

It's easy to work around this, but it would be nice if it worked.  Am I missing 
something obvious?

I don't know if it's obvious, but `match' is relying on static
information about the fields of `b', but `struct:a' is only known
dynamically.  So at expansion time, `match' has no idea how many other
fields there might be other than the ones explicitly declared in `b'.

I thought match raised an error if the static info wasn't completely known.
