The cash_out problem can't really be fixed until we do something about
subdividing type "opaque" into multiple pseudo-types with more carefully
defined meanings. cash_out is declared cash_out(opaque) which does not
really mean that it accepts any input type ... but one of the several
meanings of "opaque" is "accepts any type", so the parser doesn't reject
cash_out(2).
I'd like to see something done about this fairly soon, but it's not
happening for 7.3 ...
