You are saying there's some undocumented usage for pragmas. That's not true. use strict; matches the use Module; pattern, which is documented to be the same as BEGIN { require strict; strict->import(); }.

Anyway, pragmas refers to modules that behave in a certain fashion. There's nothing special about them as far as Perl is concerned.

pragmas are not even mentioned in require, it only talks about "library files"

First you complain that "Modul"e is too specific, now you complained that the more generic term doesn't apply.
