POSTPONE had no common practice at the time it was introduced. 18 years later we still have trouble with it. By comparison, CATCH and THROW had plenty of common practice, albeit in other languages. It has caused no trouble. The lesson is not to standardise a solution until it has been exhaustively evaluated. However, POSTPONE is a mess we have to cope with until we have a proper model of xt's and Forth compilation that allows for modern techniques. Once we have a model we can try it and define a sensible word set. STATE POSTPONE and IMMEDIATE may be casualties of this process in 20 years time.
