Not having been on an analysis course for some years, I was unaware of this fact until now. Are there ANY mathematicians who would place {n\to\infty} as a SUBSCRIPT on \lim? I would be very surprised. Similarly for \max. I would suggest that the \limits should be given explicitly for these operators at least. \def\lim{\mathop{\operator@font lim}\limits} \def\limsup{\mathop{\operator@font lim\,sup}\limits} \def\liminf{\mathop{\operator@font lim\,inf}\limits} \def\max{\mathop{\operator@font max}\limits} \def\min{\mathop{\operator@font min}\limits} \def\sup{\mathop{\operator@font sup}\limits} \def\inf{\mathop{\operator@font inf}\limits} (Substitute \rm in plain TeX.) On another point, in NFSS the private command \operator@font is used in operators. Could I suggest that a PUBLIC command be used, so that the casual user can easily define his own operators? (I am assuming that LaTeX3 will not appear for some considerable time, eg, 2 years.)
