--- Comment #20 from Mike Franklin <slavo5...@yahoo.com> --- The only reason `alias whetever this` does not use the assignment syntax is that the `alias this = existingname` conflicts with the ability to alias base (i.e. super class) constructors: `alias this = super.this`. Find a solution to that and we can finally use the assignment syntax for alias this. See discussions at https://github.com/dlang/dlang.org/pull/200 and https://github.com/dlang/dmd/pull/1341 for greater understanding of the issue. --
