Suggestion: case-sensitive imports

See original GitHub issue

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.

Can I upvote this issue?

I spent hours trying to figure out why my TeamCity build was failing only to realize that the project had some imports that were the wrong case!

Quite an unexpected gotcha as I thought OSX would not import the file if it was the wrong case.

I should add the reason why we did not do that is realPath has negative perf implications.

Make it opt-in with a flag like enforceCaseSensitiveFileSystemWithSlowerCompilerPerformance.
