The problem with this is that the slash doesn't really appear where it
should.  Try it on the letter A, which is, I think, the most common
letter to receive the Feynman slash (it is at least when I'm doing the
minimally coupled Dirac equation):

	$\not A$ 

My \slashchar works only a little better.  Try it.

	$\slashchar{A}$

But I remind you what I said in the first place:

Each character should get the slash through it in a slightly different
place.  \slashchar punts and puts it through the center.

Note also: luckily one never needs to put a Feynman slash in sub or
superscript, so that is not an issue.
