[PRL] Simon Peyton-Jones giving my class today @ 9:50

[Olin Shivers]

Simon is giving today's lecture in my compiler class,
at 9:50 in WVH 110. It's a talk on classes: OO classes,
Haskell type classes, and subclassing-considered-harmful.

Y'all might want to sit in. Simon is generally held to give
some of the best talks anyone gives in PL; you basically
can't go wrong.
