All D class objects inherit from Object.
Compare with another Object obj.
Test whether this is equal to o. The default implementation only compares by identity (using the is operator). Generally, overrides for opEquals should attempt to compare objects by their contents.
Compute hash function for Object.
Convert Object to a human readable string.
Create instance of class specified by the fully qualified name classname. The class must either have no constructors or have a default constructor.
