[REBOL] Re: Why I don't need get-word here!

Hi Patrick, On Sunday, November 2, 2003, 6:58:39 PM, you wrote: PP> So my questions are: PP> - Do I need the get-word? No, you don't in this case. PP> - Is there a difference in the result? It's the same, there's no difference. PP> two syntaxes, the same results, what am I missing ? Basically, :word always yields the same result as get 'word while word does not always yield the same result as using GET. In the recent versions of REBOL the only datatypes for which there is a difference are the ones enclosed in the ANY-FUNCTION! pseudo type. That is, while using print will cause the function to be called, using get 'print or :print will just get the value the word 'PRINT refers to, i.e. the PRINT native function. In practice you have to use :WORD only if 1) you know the word refers to a function and only want to get the function, not evaluate it; or 2) you don't know what type of value the word refers to, and you don't want it to be evaluated in the case it was a function. In particular I suggest you to use the get-word notation if your data is coming from an untrusted source.
