Bug 10697 – Syntactically Incorrect Alias This Causes Object to Conflict with Itself

import std.stdio; struct Test1 { int i; } struct Test2 { Test1 test1; alias this test1; } void main() { Test2 test2; writeln(test2.i); } /d995/f66.d(11): Error: alias f66.Test2.test1 conflicts with variable f66.Test2.test1 at /d995/f66.d(10) This also fails on GDC 2.060 and LDC 2.060, and whatever version of git HEAD dpaste is using. http://dpaste.dzfl.pl/5f8bb3f4

That's not a syntactically incorrect alias this. That is a an alias called test1 to typeof(this). Renaming test1 to something else makes the code compile (with a deprecation warning, at the time of the creation of this post, that **this** cannot be used as a type, but that's something different). The compiler cannot simply assume that you were trying to write an alias this since you could be trying to write an alias to the type of this. Closing as invalid.
