o pedantic in adhering to definitional terms
As an educator I know this software to be sweeter than most for teaching and=
learning of say, introductory programming..
The 'scratch' version is as sweet as anything for kids learning
It feels as free and open as can be, in terms of what you can see and change=
I'm not any smalltalk talk programmer, but i get how you can access the sour=
ce code and make any change whatsoever at this level..
Still...take this as wild comment from a technically na=EFve educator who is=
biased towards what works for kids learning
