since in other entries I keep having the need to directly point to it, I created a brief entry non-singular distribution.

The only proposition there currently is (here) the density of the embedding $C^\infty_{cp}(\mathbb{R}^n) \hookrightarrow \mathcal{D}'(\mathbb{R}^n)$. I should find a canonical citation that also $C^\infty(\mathbb{R}^n) \hookrightarrow \mathcal{E}'(\mathbb{R}^n)$ is dense.
