Description

TypeScript Version: 2.7.0-dev.201xxxxx

My mac does not have case sensitive imports. That is you can import the file x.js as ./X.js and everything will work. However, our servers run on linux (like most) and I got a runtime exception that took down the whole server because linux imports are case sensitive.

I think this would be an awesome addition to Typescript to prevent fatal mistakes that are hard to catch like this one.
