Why is it not "a shell?"
Because '$$' doesn't match its process ID.
OK. That's a rather unique definition, but it's a definition.
I'm not sure why I have to fight over this. It's clearly my
misunderstanding. That's why I suggest clarifications in the documentation,
if you're interested in creating a better experience for users like me.
I don't think we're fighting here. We're discussing whether or not we need
to invent new nomenclature to clarify an obscure point, or whether a
clearer explanation of the concept of a subshell will suffice.
