Un-popped push

[ghost]

In the src/plugins/flow.js override of parseMaybeAssign, there is a call to this.state.context.push(), followed by a block of code, followed by a call to this.state.context.pop().
But there is an early return inside that block of code, meaning that the push may not be popped. This looks incorrect, but naively fixing it by adding a pop() before the early return breaks some tests.
