sorry, please read \newcodes@, used in \DeclareMathOperator and doing
\gdef\newmcodes@{\mathcode`\'39\mathcode`\*42\mathcode`\."613A%
\ifnum\mathcode`\-=45 \else
\mathchardef\std@minus\mathcode`\-\relax
\fi
\mathcode`\-45\mathcode`\/47\mathcode`\:"603A\relax}
which has the \mathcode/\mathchardef issue if one has assigned
an Umathcode to -
