Thank you, like I said I wasn't sure if that was supported by the 
name of `AssignExpression` and whether it would work, but seems 
like everything is good.

So from my point of view then everything is okay.

I'm perfectly fine with this not working, because I think that 
could lead to subtle bugs.

I'm a strong believer of that if a function returns a value then 
you must use that value and should only discard it if absolutely 
necessary or if you're debugging.
