I try... unfortunately - no. :(

I extend test that it showed a error:

================================================

Trying to complete: 'def arr = array[1, 2. 3]; arr.M'
: error: expecting identifier after `.'
: error: $ operator outside quotation <[ ... ]> context
  Member found:
    MemberwiseClone  ==> method System.Object.MemberwiseClone() :
System.Object Protected
  ==========
Finished
================================================

In fact here two errors.
1. Completion engine not found "Map" and "Map2" extention methods.
2. Completion engine found protected member "
System.Object.MemberwiseClone()".
