[Bug] Parsing broken after functions with arrays as parameters

[sancarn]

Describe the bug Initially I noticed this when the Option Explicit error wasn't applicable for stdCallback and stdLambda.

Now I realise though that the outline doesn't work for these either. So I assume parsing is just broken.

Both these modules have the following declare:

Private Function stdCallByName(ByRef obj As Object, ByVal funcName As String, ByVal callerType As VbCallType, ByRef args() As Variant) As Variant
  ...
End Function

after which it seems parsing breaks

To Reproduce

Minimally you can just load stdCallback or stdLambda into vscode.

More specifically it seems to break when ByRef AND arrayQualifier () is explicitely declared...

Correct:

vs half-broken but recovers

vs fully broken

From the antlr grammar I can't see any reason why this would be failing though...

positionalParam: (parameterMechanism wsc)? paramDcl;
parameterMechanism
    : BYVAL
    | BYREF
    ;
paramDcl
    : untypedNameParamDcl
    | typedNameParamDcl
    ;
untypedNameParamDcl: ambiguousIdentifier parameterType?;
parameterType: arrayDesignator? wsc AS wsc (typeExpression | ANY);
arrayDesignator: '(' wsc? ')';

ambiguousIdentifier
    : IDENTIFIER
    | ambiguousKeyword
    ;
IDENTIFIER
    : [A-Z][A-Z0-9_]*
    ;
ambiguousKeyword
    : ACCESS
    | ALIAS
    | APPACTIVATE
    | APPEND
    ....

Thanks for reporting, but also for diving into it. I'll check it out when I get a chance (soon, hopefully).

This absolutely breaks syntax highlighting but I can't get it to break the parsing. Will attack this from a textmate grammar perspective.
