Description Timothee Cour 2016-11-21 17:39:59 UTC 
The error message is really hard to understand, and hard to reduce using dustmite (lots of large dependencies).
Could we make dmd output more diagnostic information, eg fully qualified name of aliased symbols, eg:


```
module common.d;
public import std.conv:to;
```

=>

Error: common.to(std.conv.to) at common.d conflicts with common.to(...) at common.d
Comment 1 Timothee Cour 2016-11-21 17:46:31 UTC 
update:

fun.d(19): Error: common.to at /tmp/common.d conflicts with common.to at /tmp/common.d

so it refers to the same file
Comment 2 Timothee Cour 2016-11-21 18:05:13 UTC 
ok here's a reproducible bug, turns out it's a regression:

fun.d:
import common3;
import common2;

void test(){
  auto a="12".to!int;
}

common3.d:
module common3;
public import common2:to;

common2.d:
module common2;
public:
import std.conv;
import std.datetime;

$dmd_X -c -o- fun.d
fun.d(XX): Error: common2.to at common2.d conflicts with common2.to at common2.d

$dmd_X --version
DMD64 D Compiler v2.072.0

worked with: DMD64 D Compiler v2.067.1
failed with: DMD64 D Compiler v2.068.0 (and DMD64 D Compiler v2.072.0)
