I was wondering how '? (or 'help) can take a word as an input without the word or it's function being evaluated first. Rebol evaluates from right-to-left as in:
>> return-string: does [ print "ABC" return " A string! "] >> print trim return-string
ABC A string! In that example 'return-string is evaluated first (I think), then 'trim, then 'print. So what about:
>> ? return-string
USAGE: RETURN-STRING DESCRIPTION: (undocumented) If this followed the same rule as before then the string "ABC" should have been printed before the help text. Since '? isn't a native function I can't see how it can break the standard convention. I thought
>> source ?
... would provide an answer but the output just confused the hell outta me. I have tried to write functions like this in the past but never had any success. Clearly my concecpt of the standard convention must be wrong. Could somebody clarify it for me in plain english please. SpliFF
