I'm currently developing a facility to do live updating of processes with running game loops in Go. If one were to add in dynamically loadable libraries (working in Linux, last I checked) one could have the same facility for changing a single endpoint in Go. (It could also be implemented with small executables and reverse proxies.) I think what this demonstrates is that Go isn't a better PHP. Rather, we're at the point where Go could be used to build a better PHP. The most likely paths for this, are to somehow come up with a big group of developers with a penchant for doing this, and/or have some big company fund this.
