remove-typep-transformer

Arguments: type

Removes the typep-transformer for type, if there is one. It is not an error to apply this function to a type that does not have a typep-transformer. This function returns t if there was a typep-transformer for type and returns nil if there was not. Typep transformers are added with add-typep-transformer.

See compiling.htm for general information on compiling and see Adding typep-transformers in that document for more information on typep transforms.
