A full implementation of a full design will make what people have done
so far be what they really are -- prototypes. As anyone knows that has
written software that real people use, it is a long way from a prototype
to a product -- much longer than from idea to the prototype.
You may hear some implementers complain, but it is the users who are
the important parties, and we should have a clean design for their sakes,
not a compromise.

I think it is a very bad idea to design the linear syntax around
how people "say" math expressions for several reasons, the most important
of which is the "anglo-centric" view of math. Written mathematical notation
has a universality well beyond any spoken language. It is used
and recognized in the Americas, Europe, Asia, Africa, India, etc, independent
of the user's ability to speak, write, or read English (or American English).
The closer we can make the linear syntax correspond to how it will look on
piece of paper, the more univerasal it will be.
Obviously, 2-d operators will have to be made up, but that is not
anglo-centric. I think the only place where the language will have
a anglo-centric design is in the name of the sgml-tags and character
entity names. In these two cases, we are simply following established
practices (tag names) and international standards (assuming we use SGML
ISO standard names).
