I'd definitely choose to go with making the code not compile. Otherwise, it
risks function hijacking. You could have
auto foo(S s) {...}
in my.pack which
S* s;
s.foo();
is happily calling, and then when you change the code to import your.pack with
auto foo(S* s) {...}
the code would silently change which function was being called. In general, we
try and make all such situations compilation errors in D.

Well, if pointers are dereferenced in case of accessing members, then the problem already exists and can't be reason for not accepting enhancement proposal. However, there is still a question what to do when both function are available: foo(T* ptr, ...); foo(T val, ...); I prefer to see the former to have priority over the latter. It may be useful in cases when the first one was written intentionally for e.x. to check for null pointer. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

This is duplication of 8603.
The problem is that with this approach pointers are implicitly dereferenced.
Consider function:
void foo (T type) { }
which now can be called:
T var;
T *ptr;
type.foo();
ptr.foo();
