"X, Y, Z are collectively (called, referred to as, known as) W"

I vaguely remember there being an editorial NB comment in the C++26 cycle about how we ought to get rid of the word "called" when we mean "termed, known as, referred to as," but I can't find it now. Anyway, I notice that even in the relatively small number of places where we use the formula "X, Y, and Z are collectively verbed foobarical types," we vary among several different verbs.

As of 15fc5a2f7106963d8e7904eee03bebe2aaf7a81b the counts are:

15 collectively called
 5 collectively termed
 3 collectively referred to as
 1 collectively known as

It would be nice, and seemingly achievable, to harmonize at least these 24 places to use the same verb. Unfortunately for my recollection of that NB comment, "called" is clearly the winner both in popularity and IMHO in euphoniousness: "termed" feels much too pedantic, "known" a little too tutorial, and "referred to as" much too clunky and borderline ungrammatical.

Start from commit 15fc5a2f7106963d8e7904eee03bebe2aaf7a81b and search the draft sources for “collectively called”, “collectively termed”, “collectively referred to as”, and “collectively known as”. Review the 24 reported occurrences and harmonize them to the chosen wording, then verify the draft builds cleanly and no unrelated text changed.
