I agree. After all, it is no worse than "ADD 1 TO AGREECOUNT GIVING
AGREECOUNT.".

I do have a serious concern with lack of either operator overloading or
complex primitives as one of the barriers to use of Java for engineering
and scientific programming.

The problem is not just the keystrokes for typing the expressions. It is
very important to be able to check that a lengthy expression in a
program is a correct translation of the corresponding expression, in
mathematical notation, in a textbook or paper.
