I have two problems with this. 1. The first is the the syntax `alias this` does not imply "shadowing" of the rest of the members. EG: template Foo { alias this = long; alias T = short; } //Later: Foo a; Foo.T b; //Error: T not a property of long ? What??? In this case, I think `alias this` does a bad parallel with *what* alias this actually does. 2. Ditto for functions: template foo { void this(){} void this(int i){} } //Template constructors? //No! eponymous template! Again, bad parralel between what "this" does in general case. -------- So if I placed my vote on something, it would rather it be on the "template" keyword, or anything else actually. I'm not sold on using "this". -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
