Animated GIF of the current behavior

Don’t autocomplete:

var a|
function a|
function myFunc(a|
class a|
{a|
{get a|

(Text cursor is marked by |)

The current behavior is demonstrated in the attached animated GIF.

CodeMirror provides lexical types which I was hoping to leverage.

Unfortunately, for both cases below the lexical type is the same "vardef":

    var a| <- shouldn’t autocomplete
    var a = myFunc| <- should autocomplete

Lexical type ")":

    function a(b| <- shouldn’t autocomplete
    if(myFunc| <- should autocomplete

Lexical type "stat":

    {a| <- shouldn’t autocomplete
    myFunc| <- shouldn’t autocomplete

Seems like the only case I can fix is:

    function a|

At this case CodeMirror’s lexical type is "block".

However,

    var fn = function a|

is lexical type "vardef" and

    function fn() {return function a|

is lexical type "stat". These two will still trigger pointless autocomplete.
