This meeting continues our Haskell lesson series with Echo delivering Lesson 3 on Recursion Patterns, Polymorphism, and the Prelude from Brent Yorgey's CIS194 course ( http://www.seas.upenn.edu/~cis194/spring13/lectures.html).
Lyle will give an introduction to category theory, a theory about mathematical structures and their relationships, which has applications in functional programming.
The meeting will be at Collective Agency in the Tiffany Center - the same place as the February meeting. The elevator is expected to be restored to operation by then. (UPDATE - not restored yet.) Someone will wait in the lobby to let you in as the front doors are locked after 6. The meeting is on the 8th floor.
