Malebranche also developed an original theory related to preformationism, postulating that each embryo probably contained even smaller embryos ad infinitum, like a Matryoshka doll.
However, the reader needs to be cautioned that, even though the μ operator is easily created by the base instruction set doesn't mean that an arbitrary partial recursive function can be easily created with a base model -- Turing equivalence and partial recursive functions imply an unbounded μ operator, one that can scurry to the ends of the register chain ad infinitum searching for its goal.
