A paper was published with a Fortran program to illustrate the
algorithm.  (I think the author was Morven Gentleman.)
The program had a variable like ABSX that was assigned the value
ABS(X).  Throughout the code the variable was coded as "ABS X"
since Fortran treats "ABS X" and "ABSX" exactly the same,
and coding "ABS X" makes it more obvious that the item in
and expression is the absolute value of X, and not just some
weird variable name.

After it was published a complaint was raised from someone
who did not realize that "ABS X" was just a variable that
had been assigned ABS(X) and though that the program depended
on some non-standard compiler feature that was turning
"ABS X" in to the actual function call ABS(X).
