Hello. I've found next bug:
If you do a constructor call with a function which has an error, and create variable with that call, that variable won't ever be accessed.

Steps to reproduce:

node
> function WrongClass() {
... thio.a = 5 // lets asume we have typo error here
... }
undefined
> a
ReferenceError: a is not defined
> let a = new WrongClass()
ReferenceError: thio is not defined
    at new WrongClass (repl:2:1)
> // Now we have an error and we are trying to redeclare a
undefined
> let a = 3
SyntaxError: Identifier 'a' has already been declared
> // Oops! Allright, lets try this
undefined
> a = 4
ReferenceError: a is not defined
> // So is it defined or not? Whaatt??
undefined

It is really inconvenient that this is the case but there's little we can do to change this (maybe we should consider to work around this though as a lot of people run into this issue).
