I don't know how VisualD works, but to provide auto-completion it 
should be able to compile a source code for autocompletion 
information, because simple analyzer would not work with variadic 
templates like opIndex(Indexes...)(Indexes indexes).

Nitpick: t3[0][0][0] is much slower than t3[0, 0, 0].
