Internal DSL technique using a series of unrelated calls.

Characteristics

This implementation demonstrates the Internal DSL pattern called Function Sequence. Function Sequence consists of a series of unrelated calls, which are ordered in a sequence but only by time of execution. There is no data relationship between the calls, thus context variables are needed. Another possibility is to use Object Scoping. Another thing thats needed are global functions or some kind of namespace control in your used language. This implementation uses Java and benefits of the static imports.

Function Sequence is ideal for DSLs high level statements and should normally be combined with the other Internal DSL techniques like Method Chaining and Nested Function
