((SystemNavigation default allImplementorsOf: #instance) select: #isMetaSide) size. "10"

((SystemNavigation default allImplementorsOf: #singleton) select: #isMetaSide) size. "1"

This reminded me of this��https://twitter.com/ID_AA_Carmack/status/575788622554628096

considering we already use a/an for parameters, this can be quite fitting.

But some consensus would be nice�� personally I don't really like that I have to think about the fact that it is a singleton, so The* + #new sounds interesting.

Otherwise to me #current sounds much more fitting than #default (in fact I would expect them return different things if #current: has been used).
