No clarity at all when the brain switches between coordinate
system conventions, row or column major order, and similar
non-Ada ways of expressing things. Since the semantics of
any program calling Arctan is not changed if the parameter
name X becomes <<unambiguously-denoting-what-we-mean>>, thus
since there will be an absolutely safe change set if such
a name were introduced, isn't it about time to get rid of
names that only a high school delusion holds up against?
