Me too!

Have you learned any tricks for getting up to speed on large code bases with very limited static typing?

In recent years I've mostly worked on large, complex Python systems. The consequences of (undisciplined) dynamic typing not only sapped my joy in programming, it really burned me out.

Some people are really good at living with code bases like that. I'm not one of them, but I'm still hoping to find some way to bridge the mental gap.
