The attached patch to clojure.core fixes the printing problem for
types that have no implementation of print-method. When such objects
are printed or converted to strings, an infinite loop leads to a
stack overflow. The reason is that the :default implementation for
print-method calls str on the object, which in turn calls print-
method again.

print-method calls str on the object, which in turn calls print-
method again.
The path makes two changes:
1) The current :default implementation becomes the implementation for
Object, thus remaining the default for everything that does not have
a type field in the metadata.
2) A new :default implementation calls print-method recursively after
having removed the :type field from the object's metadata.
