Expectations:

• No error to be thrown. (And if one were to be thrown, I'd expect a real
  Error to be thrown, not an Array.)
• An AST to be returned.

The non-JS version of the parser seems to have the same problem:

~/bugs/flow-parens-string-bug  
❯ npm i flow-bin
/home/lydell/bugs/flow-parens-string-bug
└── flow-bin@0.38.0 


~/bugs/flow-parens-string-bug  
❯ echo '("a")' | flow ast --pretty
Unhandled exception: Failure("Nooo: T_LPAREN\n")
