Nothing prevents the system to add a stack trace on the Error branch of an Either. It's just that some evaluation strategies [lazy] that are usually associated with functionally programming [Haskell] provide unusual reduction traces.

The language is intriguing, combining logical and functional paradigms is potentially very powerful. That being said, a quick read of the document doesn't quite illustrate how to harness the [potential] power. Most of the language desc

In practice, one can check the Dockerfile lineage of a given Docker image and assess the quality of the commands. Good practices are to use package managers with explicit versions, for example "apt-get install subversion-tools=1.3.2-5~
