Comment:
Well, first of all, we didn't have that property before. The counterpart
to {{{show}}} is {{{read}}}, not {{{readFoo}}}. We did however have the
property:
{{{
prop_idempParsePrint x = (r . s . r) x == r x
where r = readPackageDescription; s = showPackageDescription
}}}
I agree that this would be nice to have, though.
