% \subsection{(Big) operators}
%
% The engine does what is necessary to deal with big operators for us
% automatically with \cmd\Umathchardef.
% However, the limits aren't set automatically; that is, we want to define,
% a la Plain \TeX\ \etc, |\def\int{\intop\nolimits}|, so there needs to be a
% transformation from \cmd\int\ to \cmd\intop\ during the expansion of
% \cmd\_@@_sym:nnn\ in the appropriate contexts.
%
% \begin{macro}{\l_@@_nolimits_tl}
% This macro is a sequence containing those maths operators that require a
% \cmd\nolimits\ suffix.
% This list is used when processing |unicode-math-table.tex| to define such
% commands automatically (see the macro \cs{@@_set_mathsymbol:nNNn}).
% I've chosen essentially just the operators that look like integrals;
% hopefully a better mathematician can help me out here.
% I've a feeling that it's more useful \emph{not} to include the multiple
% integrals such as $\iiiint$, but that might be a matter of preference.
%    \begin{macrocode}
\tl_set:Nn \l_@@_nolimits_tl
  {
    \int\iint\iiint\iiiint\oint\oiint\oiiint
    \intclockwise\varointclockwise\ointctrclockwise\sumint
    \intbar\intBar\fint\cirfnint\awint\rppolint
    \scpolint\npolint\pointint\sqint\intlarhk\intx
    \intcap\intcup\upint\lowint
  }
%    \end{macrocode}
% \end{macro}
%
% \subsection{Radicals}
%
% \begin{macro}{\l_@@_radicals_tl}
% The radicals are organised in \cs{@@_set_mathsymbol:nNNn}.
% We organise radicals in the same way as nolimits-operators.
% (\cs{cuberoot} and \cs{fourthroot}, don't seem to behave as proper radicals.)
%    \begin{macrocode}
\tl_set:Nn \l_@@_radicals_tl {\sqrt \longdivision \cuberoot \fourthroot}
%    \end{macrocode}
% \end{macro}
%
% \subsection{Fontdimens}
%
%    \begin{macrocode}
%&lt;*LU&gt;
%    \end{macrocode}
%
% \begin{macro}{\@@_mathparam_restore:}
% \cs{glb@settings} might not be necessary but is included for symmetry.
% If the maths font were to be loaded later it would clobber our mathparam settings, so
% this seems like a sensible move.
%    \begin{macrocode}
\@@_cs_new:Nn \@@_mathparam_restore:
  {
    \glb@settings
    \tl_use:N \g_@@_mathparam_settings_tl
  }
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\@@_mathparam_store:}
% \cs{glb@settings} is called to force maths fonts loading \emph{now} so the mathparams
% are up-to-date.
%    \begin{macrocode}
\@@_cs_new:Nn \@@_mathparam_store:
  {
    \glb@settings
