           Summary: "No property x for type Y" error not as helpful as it
                    should be
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: dmd

          Reporter: elpenguino+D at gmail.com

```
auto x = ["a","b","c"];
auto y = x.joiner();
```
Given code like this, the compiler will issue a `Error: No property joiner for
type string[]` error. Changing the second line to `joiner(x)` will give a more
useful `Error: joiner is not defined, perhaps import std.algorithm; is
needed?`.

The former error message should be made to be more like the latter. It should
address the possibility of UFCS and suggest the same import.
