I am a retired software developer. I retired at the end of 2003 and since then my computer programming activities have been for recreational purposes. I find Mathematica excellent for that.

I started using Mathematica in 1997 (Ver. 3). I am currently using Ver. 9. Although I have used Mathematica for all kinds of stuff, I use it mostly to pursue my long standing interest in Euclidean geometry, both in the classical Greek synthetic form and in the more modern analytical form.

comment Explicit use of Evaluate not behaving the way I expect it to
... But, despite the relationship, I assert that this question is sufficiently different that less experienced users, should they follow the link, will be more confused than enlightened. Should this question be reopened, I suggest the link to the other question be given in a comment.

comment Explicit use of Evaluate not behaving the way I expect it to
I feel compelled to ask for the reopening of this question. I do not think it duplicates the question Mr.Wizard identifies as being duplicated. This question is about the explicit use of Evaluate at different levels of an expression and it's interaction with SetDelayed. The other question is about the explicit use of Evaluate and it's interaction with Function. For experienced Mathematica users, the two question are related, so it is no coincidence that part of Mr.Wizard's answer to the other question is applicable to this question. ...
