I just came across the following claim:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\lim_{\hbar\rightarrow 0}[\frac{1}{\hbar}(AB-BA)][/tex]

(which approaches the classical Poincare commutator) is a derivative with respect to [tex]\hbar[/tex]. I know itlookslike derivative, but is it really? Please elaborate.
