  Ideas from deformation quantization are applied to deform the expression of
elements of an algebra. Extending these ideas to certain transcendental
elements implies that $\frac{1}{i\h}uv$ in the Weyl algebra is naturally viewed
as an indeterminate living in a discrete set $\mathbb{N}{+}{1/2}$ {\it or}
${-}(\mathbb{N}{+}{1/2})$ . This may yield a more mathematical understanding of
Dirac's positron theory.
