[REBOL] Re: can't quite get it right...

The above function could be trimmed a little bit: uppercase?: func [ ch [char!] ][ return either all [(ch >= #"A") (ch <= #"Z")][true][false] ] We can trim out the either and the return as well: uppercase?: func [ ch [char!] ][ all [(ch >= #"A") (ch <= #"Z")] ] Although this last one returns none instead of false, it can still be used, since logically none is equivalent to false. You can use it in an if statement. :)
