Agda II -- Take One I will present the first version of the Agda II language and some of the motivations behind it. In particular I will talk about what is in the language: * implicit arguments * datatypes and functions by pattern matching * fancy module system and what is not: * pi in set * signatures and structures * inductive families and try to convey the reasons why this is so. The presentation will be accompanied by a healthy amount of simple examples illustrating the syntax of the language and how the different features can be used.
