Ah yep, that makes sense. Thanks for the detailed explanation :) Actually, you just reminded me of my recent experience of delving into Go -I wrote a simple script to read in n YAML files from a directory and merge them into one, we're using the Prometheus JMX exporter which only accepts one YAML file, but using several smaller, more focused configs kept the complexity down. I used Go to produce a standalone binary so that everything needed could be brought in from a tiny Docker image as a mixin. Go's default of building standalone binaries is what tempted me, it was far easier to use Go in a multi-stage build to create a static binary than it was to try to provide the same using Python etc. But yeah, opening a directory, reading its contents, and then consuming all the files within it required five "if err != nil" blocks. But all I really needed was for an error in stage N of the chained IO operations to propagate through the pipeline so that the result of using the pipeline was Some(x) or None.
