           Summary: Lambda template literals
           Product: D
           Version: D2
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: DMD
        AssignedTo: nobody puremagic.com
        ReportedBy: bearophile_hugs eml.cc



Currently (DMD 2.058head) this kind of code is not allowed, but I think it's
handy to have (I suggest to require the () around the lambda template):


void main() {
    alias (x =>  x ^^ 2) sqrTemplate;
}



Timon Gehr reminds me that the semantics of that code is already available,
just with a longer syntax:


template ID(alias a){alias a ID;}
void main(){
     alias ID!(x => x ^^ 2) sqrTemplate;
}

A note from Philippe Sigaud:

 If you do an enhancement request, could you also add one for:

 alias __traits(whatever, whatever) some Result;

 Right now, the alias grammar doesn't allow this and I find this
 limitation jarring.
