Looks like the last meeting was May. Is there going to be another one?
Alternatively, we could just fold this into the normal functional programmers meetup.
Incremental Algorithms on Lists

Incremental computations can improve the performance of interactive programs such as spreadsheet programs, program development environments, text editors, etc. Incremental algorithms describe how to compute a required value depending on the input, after the input has been edited. By considering the possible different edit actions on the data type lists, the basic data type used in spreadsheet programs and text editors, we define incremental algorithms on lists. Some theory for the construction...
I think we should do something vanilla; something highly practical; something everyone can use.
