First of all cool concept. I'm looking forward to playing with the DE even if it doesn't replace my daily DE. In my experience, extending an existing project in Go is much faster than lower level languages. The opinionated build and dependency system can seem limiting but really helps one get up to speed quickly on a new project. Just setting up a build environment for a low level language based project can be enough of a hassle/time sink to dissuade me from attempting with a quick toy project.
