Should we ask Matz to rename the singleton to the "nonce"? How about
a new keyword for referring to the singleton ...

class << self
...
end

becomes

nonce self do
...
end

how about

module Kernel
def nonce( arg, &block )
n = class << arg; self end
return n.class_eval(&block) if block_given?
n
end
end


I do like the word, though -- etymology is fun!

We'll, I think it's enough to point out that this term is there. It's a
got a classy feel to it, "nonce class", which is nice. So we can all
just sort of maul it over and we'll see if it perculates upward. For
starters I'm using it when I assign it to var, eg. nonce =
(class<<self;self;end)

Like that. Never really cared for the << notation since it looks like
appending to an array or string, etc.

:-) Definitely. I was quite floored to find an honest ot goodness
synonym for singleton. And it's obscure enough so it doesn't have any
significant connotation baggage, which is great.

An occassion need not be limited to an instantaneous moment. Could I
not say, "I have occassion for an Eigenclass"? It also has other
connotations, such as "need".

I don't think any word is ever going to be perfect, precisely becuase
there is no precise word for it. We have to define one. And the problem
with "singleton" is that it's already taken.

I've never perceived a problem there. "Singleton" is used in different
circumstances, as is "nonce." Much of meaning depends on context.

But "nonce" does carry a strong connotation of "one-time usage."

Honestly. Have you ever even used the work _nonce_ in your entire life?


Right. So how "strong" can any connotation possibly be? The idea here
is clearly to give it a new connotation --that's the point. With
Singleton, it's not just a connotation but rather a complete
redefinition of an already accepted term in OOP parlance.

I have used it many times over the last twenty years, mostly in
the phrase "for the nonce."

Also in the contexts of cryptography, mathematics, and Lojban.
