Improvement: Better broken code parsing.

[vburenin]

In the following example the parser could try and recover from the error better so that the remainder of the code can still work out:

package demo

func foo(&int) {

}

A quickfix for this would be to convert any & to * character but it can be addressed at a later time.

Original issue

This code sample contains a typo where instead of * I copy-pasted &, just because of that all autocomplete capabilities within this method are disabled. Code is not recognized.

It would be nice to have this error highlighted and all other functionality working.

@ignatov I'm attempting to work on this.

Where should I add the quickfix that should run for the issue above? I've made some work for this but when it comes to parameters inside function declarations I don't know where this gets triggered.

As for the parser itself, I still need to dig a bit to see how this could be improved (and I'm not familiar with that part of the plugin).

Thanks.
