Flow parser cannot parse simple Literal in Parenthesis.

[danez]

The following code makes the flow-parser fail. All other parsers have no problem with it.

("not a directive");

The message I receive is:

Non-error thrown with value: [ 0,
  [ 248, aw { t: 0, c: 'Failure', l: 7 }, -3 ],
  aw { t: 0, c: 'Nooo: T_LPAREN\n', l: 15 },

ASTExplorer with flow also fails (see dev console):

Noticed this while working on babel/babylon#277 and using the flow-parser as reference parser to compare the ast from babylon to.
