This doesn't bother me. We will almost always have the word "class"
or "pattern" following the word "singleton." No ambiguity. We do
sometimes talk about a Singleton (without the word "pattern"), but
then it is always capitalized.

There are also singleton methods; and I think some people refer to
objects that possess singleton methods as singletons. However, it's
always possible to clarify your meaning by the simple addition of
a single word.

I think the important thing is to know the meaning of the word
"singleton"; and then its specific meaning in context will be made
clear. (FWIW, it's used in card games also.)
