(function(){
  try {} catch(e) {
    var a;
  }
});

edit: removed function declarations because they're illegal in that position.

I've moved some of my files to ES6, with "import" statements.
This is accepted by escope only with the options { ecmaVersion: 6, sourceType: 'module' } (see this comment).
Now eslevels doesn't pass options to escope line 314.
Adding the option solved my issue (confirmed by patching in eslevels.js in /usr/lib/node_modules)

Would you consider adding the option? Maybe an escope field in the eslevels options...
Thanks,
Eric

See in the example screenshot, where there is an anonymous function assigned to a var. Note that the ; after the assignment is included with the function scope coloring. This ; should be the same color as the parent scope. I have also seen this when passing an anonymous function as an argument to another function... the char after it is included, which is a bit confusing. It seems there may be an 'off by one' error somewhere which is including the additional character.

This may be an esprima bug..

function foo() {
	var y = 3;
	var w = function baz(){
		var p = 2;
	};
}

In that code, the identifier baz should be in the same scope as var p (aka, level 2), since identifiers of named function expressions are always in their own function's scope (and read-only), not in the containing scope.

However, I tried this on the demo page (http://mazurov.github.io/eslevels-demo/) and it's incorrectly identifying it in the outer scope (level 1), the same as var y.
