I used that phrase (with correct spelling). I had supposed that it would
be recognised as a variation of 'Global variables considered harmful',
(William Wulf and Mary Shaw, ACM SIGPLAN Notices, 1973, 8 (2) pp. 28--34).
I think nested variables have the same troubles as global variables, so
they should be used with care.
