Description thelastmammoth 2012-04-20 23:30:22 UTC 
//this works
class A{ int x; }
int fun(A a){return a.x;}
void main(){A a=new A; auto x=a.fun;}

//this doesn't work:
unittest{
class A{ int x; }
int fun(A a){return a.x;}
A a=new A; auto x=a.fun;
}
Comment 1 thelastmammoth 2012-04-25 00:34:07 UTC 
EDIT:
more importantly, it also fails if fun() is defined inside a function:

//this doesn't work:
class A{ int x; }

void myfunction(){
int fun(A a){return a.x;}
A a=new A; 
auto x=a.fun; //fails
}

The original test case now works in DMD git head. However, the one given in comment #1 still doesn't work.

This bug report is not valid as per the spec [1] (point 7): "Functions declared in a local scope are not found when searching for a matching UFCS function. Neither are other local symbols, although local imports are searched."
