Probably because it wouldn't make much sense.  Either the only way you 
could access age in the above is by matching Bar { age = x }, which is 
not very useful (you might as well have Bar of int, or a tuple for 
multiple fields), or the record type needs to have a name so that x in 
the pattern Bar x has some printable type.
