It seems ActionScript (not completely ECMA-compatible) adds an 'object'
primitive, which is used when an object doesn't cast down to
any real primitive. I might be wrong, but I think we do have testcases
for this from swfdec too.

Weird, I tought Number was an instance of Function. Can you check this ?

Are the results from the proprietary player or gnash ?
