What if type inference felt like a real-time conversation, instead of emailing code back and forth?

With type inference, compilers are faced with a difficult task: intuiting what types a user had in mind (but didn’t write down) while writing some code. It all falls apart when the types that the algorithm assigns are different from those the user expected, and especially so when the type error reported is far away from the site of mental mismatch.

For the web-based everything notebook that I’m working on, I’ve been writing backend hookups to various programming REPLs, including IPython and Gorilla. I wanted to be able to evaluate rust code as well in this notebook environment, and so I set about writing a simple server that would compile up a string in rust when asked. This proved do have a couple of gotchas, so I thought I’d air my thoughts here.
