I read this article but am having a hard time understanding the point in concrete terms. What does it mean to make invisible glue code first class? How would reduce the #LOC, which is something the author mentioned many times?
A powerful language to describe what needs to connect to what (similar to the Unix pipe) could perhaps make the glue code much more obvious and concise. Whether that's achievable is the question the author is asking, and apparently trying to answer.
