Really interesting comments here. I haven't found an appealing option for scripts and CI ( I think I am allergic to yaml ), bash is just way too fragile. So I've decided to write my own scripting language that is written in Go, similar in many ways to Lua, but with first class support for executing other commands, running API tests, and manipulating data. Currently dogfooding with plans to share in a few months once I'm confident it's good to start getting feedback. So, one executable plus your scripts, cross platform, no yaml.
