Describe the bug
We see an unexpected error in the code below. Replacing use type Bar\{Bar}; with use type Bar\Bar; is a workaround for this issue.
Standalone code, or other way to reproduce the problem
namespace Foo;
use namespace Bar;
use type Bar\{Bar};
final class FooBar extends Bar {
const Bar\my_type CONFIG = shape('a' => 'b');
}
namespace Bar;
abstract class Bar {
const my_type CONFIG = shape('a' => 'b');
}
type my_type = shape('a' => string);
Steps to reproduce the behavior:
Run hh_client on the above
Expected behavior
No errors
Actual behavior
File "/root/foo.hack", line 6, characters 28-30:
Some members in class `Foo\FooBar` are incompatible with those declared in type `Bar\Bar` (Typing[4348])
File "/root/foo.hack", line 13, characters 9-15:
Expected `shape('a' => string)`
File "/root/foo.hack", line 7, characters 10-20:
But got `Bar\Bar\my_type`
