Yeah. The way it's written fails to show, except via formatting,
that IMMUTABLE/STABLE/VOLATILE are mutually exclusive; and then
somebody came along and destroyed the formatting. I agree both
with adding braces and with putting LEAKPROOF on its own line.
The latter is/should be only cosmetic; but the rest of the list
has one line per independent option, and LEAKPROOF is surely
independent of the volatility options.
