"Biphasic programming" is also present in frameworks like Apache Spark, Tensorflow, build tools like Gradle and code-first workflow engines. Execution of the first phase generates a DAG of code to be executed later. IMO the hardest thing for newcomers is when phase 1 and phase 2 code is interleaved with no immediate clear boundaries, (phase 1 code resembles an internal DSL). The docs need to teach this early on to avoid confusion. A prime offender of this is SBT, with its (perhaps no longer true) 3 stage rocket, which is not really described in the docs (see https://www.lihaoyi.com/post/SowhatswrongwithSBT.html#too-many-layers-of-interpretation https://www.lihaoyi.com/post/SowhatswrongwithSBT.html#too-ma...)
