How to prepare for an oral exam
like for instance the compiler construction course.
Type systems: the strong, the strict and the safe.
Or the weak, the loose, and the unsafe. But does it mean anything?
Worklist algorithms
A small amount of background information (best read in the context of the first sets)
How to write a parser for the first time, e.g. for the oblig

How to implement implement regular expression matching
Or maybe how not to implement it?

Sound & (in-)complete proof system for first-order logics
Some clarification (I hope)

Mono- vs. polymorphic let
In the lecture, we covered type inference for generic polymorphism in a typed calculus with higher-order functions, including recursive functions and let-bin...
Type inference (Algos W and J …)
Some remarks about variations on the theme
