Yes, and yes, that's why you missed Eliot's answer ;) http://permalink.gmane.org/gmane.comp.lang.smalltalk.pharo.devel/55024 Nicolas but I see two questions popping out of this: (1) is source an object in Smalltalk; (2) in which languages/systems is source an object? > > This is an interesting debate. > > Bill > > > ________________________________________ > From: [email protected] > [[email protected]] On Behalf Of Eliot Miranda > [[email protected]] > Sent: Tuesday, October 18, 2011 1:43 PM > To: [email protected] > Subject: Re: [Pharo-project] IS Smalltalk Source also an object? > > On Mon, Oct 17, 2011 at 1:35 AM, Marcus Denker > <[email protected]<mailto:[email protected]>> wrote: > > On Oct 17, 2011, at 10:25 AM, Guido Stepken wrote: > >> Hi, there! >> >> I had a nice conversation about Smalltalk among software architects: >> >> I claim smalltalk to be the only programming system, where source is an >> object too, with all advantages and disadvantages! >> >> Am i right? >> > No, source is ascii text in Smalltak, and it's on the disk even. > > Hang on.
