Is this a bug report?
Yes, this is a bug report.
I get a syntax error with the following code, which I reduced as much as possible to just trigger the error:
constfirst=async<Xextends{}>()=>{awaitsomething();};constsecond=async<Yextends{}>()=>{};Did you try recovering your dependencies?
Yes, but recovering didn't help.
Output of yarn --version:

Steps to Reproduce
See "Reproducible Demo".
Expected Behavior
I wouldn't expect a syntax error (other errors with this code, yes, but no syntax error)
AFAIK the code is valid TypeScript.
Actual Behavior
Syntax error:
Failed to compile.
./src/index.tsx
SyntaxError: /Users/sebu/Desktop/2019-02-08-cra-ts-syntaxerror/src/index.tsx: Unexpected token, expected ";" (5:24)
