[docs] [issue22167] iglob() has misleading documentation (does indeed store names internally)

Roy Smith added the comment: The thread that led to this started out with the use case of a directory that had 200k files in it. If I ran iglob() on that and discovered that it had internally generated a list of all 200k names in memory at the same time, I would be pretty darn surprised, based on what the docs say now. We're shooting for principle of least astonishment here. ---------- _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue22167> _______________________________________
