Deno really shouldn't run TypeScript files directly. Not only is TypeScript too slow for this, it receives far too many breaking changes.
How will Deno decide when to upgrade its TypeScript compiler version? Will Deno have to have breaking changes every three months or so?
Also, Deno appears to allow import TypeScript files with .ts extensions while tsc doesn't. This alone means the same code won't run in Deno and compile with tsc.
JavaScript at Stage 3 and above is a stable compile target, and Deno should just run that.
