IIUC, technically the "pattern" here is just /foo/ -- or, rather, the
string 'foo' but there are many places where patterns are bounded by
slashes.
Everything between /foo/ and /g is the replacement string, or in this
case, '\=' plus the replace-expression.
I would call the whole line a substitute, or to be more precise, 'a
":substitute" command'. Calling it a "pattern" is in this case an abuse
of language, which may perhaps be condoned in informal text since the
context is clear.
(And, yes, I'm a retired teacher, and I can be quite a pedant when it
suits me.)
Best regards,
Tony.
