QueryDict has_key() calls __getitem__ instead of __contains__

When I try to something like:

if request.FILES.has_key('key'):


If the key does not exist, an exception is raised. Looking at the stack trace, I see that getitem was called. Shouldn't has_key map to contains?

This appears to only happen if no file was uploaded. If a file was uploaded, then has_key() behaves as expected.

has_key() is looking for a key (hence getitem()), not a value. contains() would be looking for a value ... or am I missing something?
