Just as a contrasting point, I've been reading this thread on gmail
with a proportional font. I went and looked at the PEP in a fixed
width font earlier, and the @ sign doesn't look anywhere near as bad
there.

In Courier New:

S = (H @ beta - r).T @ inv(H @ V @ H.T) @ (H @ beta - r)

Still looks kind of bulky to me, because @ is the height and width of a capital letter. How about prefixing * with an innocuous backtick?

S = (H `* beta - r).T `* inv(H `* V `* H.T) `* (H `* beta - r)

That way no part of the operator extends to the baseline, so identifiers and parentheses/brackets are visually well-separated from this as they are with most other binary operators.
