I've been thinking the same thing. We're constantly reading pointless proposals on this list. It's getting really old. Kind of hard to enforce though...
(How many proposals actually become features? I'm betting on zero.)
A proposal has the following properties:
1. The proposer wants it incorporated in a future Lua and is
not interested in ways to achieve the same effect by exploiting
current features.
2. The proposer continues arguing, rebutting all criticism, even
when almost nobody seems to like the proposal.
A suggestion has the following properties:
1. Well thought out, so that everything that needs to be said
is said and everything irrelevant is omitted.
2. The poster offers it as something to be discussed and does
not enter the discussion again unless requested to.
