+
+* Flow Control
+** Normal stepthrough
+Default mode. The commands get executed in order, with the next receiving the results of the former.
+** Alternatives
+All blocks get executed, the result of the first succeeding one gets taken.
+* Assumptions about websites that turned out false
+** Separate areas are clearly recognizable in the DOM hierarchy
+Instead, sometimes a document has to be "split" at certain elements. Alternatively, virtual blocks have to be extracted where certain elements are contained.
+** In JSON, keys are static
+Sometimes, things happen like that the keys are city names.
+
+* Implementation discoveries
+** Code interpretation
+Smalltalk code can be interpreted to create a Block. Example:
+#+begin_src smalltalk
+increaser := Object readFrom: '[ :anObject | anObject + 1 ]'.
+increaser value: 1. "=> 2"
+#+end_src
