TDPL, p.117, last para:

Really? I thought the convention was toHash (TDPL, p.205). So, which is
it? Which *should* it be?
To me, it seems utterly arbitrary that classes should use toHash whereas
non-class user-defined types should use opHash. Shouldn't we make it
consistent across the board?
I expect that opHash was a mistake and that there should be an errata
for that line on page 117: http://erdani.com/tdpl/errata/

Actually, I looked, but it wasn't listed.
Andrei? Is this an error?
Most likely!
