90 – local object.d overrides real object.d causing crash

[object.d] (an empty file)
[bug.d]
class A {}
void main() {}
C:\>dmd bug.d
bug.d(1): identifier 'Object' is not defined
bug.d(1): Object is used as a type
Assertion failure: 'b->type->ty == Tclass' on line 286 in file 'class.c'
abnormal program termination
The presence of an object.d file in the local directory overrides the real and required object.d in the dmd directory. This results in weird errors and a compiler crash.
FYI: Removing the class declaration from bug.d avoids the issue.
Suggestions (one or more of these would be nice):
1- Refuse to compile reserved file names.
2- Rename the reserved files to something less likely to collide.
3- Ignore reserved files (and .obj files for them) in any directory but the expected dmd directory.
Obviously doing #2 only, will only partially solve the problem (there remains a chance it will occur in the future), but, it does make the complete solution, involving #1 or #3, less likely to be a problem when a collision does occur.
