templated alias/enum does not capture arguments

[rainers]

Reported by Manu:

// cursor here  ------------------>  vvvvvvvvvvv    and press F12
alias isValidPixelType(ElementType) = ElementType;

// cursor moves to here:
template ElementType(Img)  // <- except the cursor goes to the start of the line rather than the proper token
{
    alias ElementType = void;
}

// the cursor should move to the template argument for the template it's in, not some other declaration with the same name

//===========================================================================================================================================
//===========================================================================================================================================

// cursor here    ----------------->  vvvvvvvvvvvv    and press F12
enum isValidPixelType(ElementType2) = ElementType2;

template ElementType2()  // <- note that I removed the template argument
{
    alias ElementType2 = void;
}

// the cursor no longer moves anywhere

//===========================================================================================================================================
//===========================================================================================================================================

template ElementType3(Img)    // <=========   To the declaration
{
    // cursor here and press F12
    //    vvvvvvvvvvvv
    alias ElementType3 = void;
}
//
// I feel like it should move to here ===//

(Not so sure what should happen in the third case). Seems like the template arguments of the alias/enum definitions are ignored in symbol lookup.

The 3rd case feels controversial. but I feel like it would make sense for the definition of the template value to lead back to the template declaration (the first line).. I doubt that has any knock-on effects, whereas I suspect the first 2 cases may lead to more complex interactions in other cases.
