These expectations should be documented clearly in a CONTRACT docline in the decorator's godoc.

NOTE: Any application that uses GasMeter to limit transaction processing cost MUST set GasMeter with the FIRST AnteDecorator. Failing to do so will cause transactions to be processed with an infinite gasmeter and open a DOS attack vector. Use `ante.SetUpContextDecorator` or a custom Decorator with similar functionality.
