.... and I have to say I was rather pleased and then a little saddened when I
became unsure of exactly what I can do with it?
Is it just a means of trying out different expressions in the same window,
as it only seems to run the last expression I enter - much like the standard
Expression Evaluation? If it does only run the last expression in the text
area, what is it's purpose? I suppose it might be a means of seeing multiple
tried expressions in the same window, but that seems a bit pointless too?
