Coverage: Destructuring named arguments of a function

[migueloller]

// repro.js

/* @flow */

function fn1(arg: number) {};

function fn2({ arg }: { arg: number }) {};

Running flow coverage --color repro.js yields the following output:

/* @flow */

function fn1(arg: number) {};

function fn2({ arg }: { arg: number }) {};

Covered: 75.00% (3 of 4 expressions)

where arg from fn2 is marked as uncovered (red). Is this an issue with coverage or am I missing something?

This does seem like an issue with coverage mishandling destructuring

Any status on this? Just experienced that as well.
