They said the prototyped in a few languages before settling on Go. Based on what you said it sounds like they didn't do a great job at that and stuck with their decision anyway.

It's been working fine for a few years now. The only problem I know is there is little to no reflection allowed (by design) so a lot of code out there is not compatible with it yet. Not sure if that's what turned the TypeScript team away from it.
