Oh my. Yeah, unfortunately given the syntax here, TS parses it thinking it’s a massively-nested JSX expression, starting here and continuing to deepen the stack at ~every <T> that follows.

   findIndex:
      & (<T>(
        array: $ReadOnlyArray<T>,
        predicate?: ?Predicate<T>,
        fromIndex?: ?number
      ) => number)
      & (<T>(
        array: void | null,

It looks like the problem starts at the {| block, where the | throws the parser into an expression context. There’s an easy fix - if the token at the start/end of an object type block is |, just issue an “invalid character” error (so people don’t start writing this in TS, for now) and skip it.

I presume this is unlikely to affect the outcome of this issue, but just to follow-up: Opening lodash_v4.x.x.js in a new editor, then running “Developer: Restart Extension Host”, will also cause the crash even after adding ./flow-typed to exclude in the jsconfig.json file.
