"Elegance" was mentionned more than once at the Boston meeting as a
"requirement" but it was not written down as a formal requirement because
it is implicit in the design process. Truly I think elegance is such a
strong requirement in all that we do that it is a design principle.
I'm sorry, but if it takes more than one line of code to define a 2D point
record, then the record system is not elegant. Moreover, I view
"extensibility" as such a strong requirement that it is a design
principle. This is why I believe a syntax based on keywords, like the one
I proposed, is necessary.
What I don't understand about your comment is that you say we will never
agree on the syntax so any syntax will have to do and then when I say
syntax is very important and the syntax I propose is better (succinctness,
readability and extensibility while having the same expressive power as
your proposal) you seem to not want to discuss it. I just don't
understand what the problem is.
