[Issue 2889] Alias this properties don't overload with non-alias this properties.

See http://www.digitalmars.com/d/2.0/hijack.html for the rationale. Overloading is done explicitly with alias just like you use using in C++ for this purpose. Unfortunately you can't alias arr.length length; in this particular case though: Error: alias test.ArrayWrapper.length cannot alias an expression arr.length The only option is to use a small function that wraps arr.length I guess. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

I think this is a language design, not a bug.
In normal class inheritance, derived class method doesn't overload with base
class methods that have same names.
class Array // the synonym of uint[]
{
size_t length(){ return 0; }
void length(size_t n){ }
// built-in length property (getter and setter)
}
class ArrayWrapper : Array
{
void length(uint l) {}
// length overrides Array.length, not overloads
}
