+% \subsection{Hooks into \LaTeXe}
+%
+% Switching to a different style of alphabetic symbols was traditionally performed with
+% commands like \cmd\mathbf, which literally changes fonts to access alternate symbols.
+% This is not as simple with Unicode fonts.
+%
+% In traditional \TeX{} maths font setups, you simply switch between different `families' (\cmd\fam), which is analogous to changing from one font to another---a symbol such as `a' will be upright in one font, bold in another, and so on.
+% In pkg{unicode-math}, a different mechanism is used to switch between styles. For every letter (start with ascii a-zA-Z and numbers to keep things simple for now), they are assigned a `mathcode' with \cmd\Umathcode\ that maps from input letter to output font glyph slot. This is done with the equivalent of
+% \begin{Verbatim}
+% \Umathcode`\a = 7 1 "1D44E\relax
+% \Umathcode`\b = 7 1 "1D44F\relax
+% \Umathcode`\c = 7 1 "1D450\relax
+% ...
+% \end{Verbatim}
+% When switching from regular letters to, say, \cmd\mathrm, we now need to execute a new mapping:
+% \begin{Verbatim}
+% \Umathcode`\a = 7 1 `\a\relax
+% \Umathcode`\b = 7 1 `\b\relax
+% \Umathcode`\c = 7 1 `\c\relax
+% ...
+% \end{Verbatim}
+% This is fairly straightforward to perform when we're defining our own commands such as \cmd\symbf\ and so on. However, this means that `classical' \TeX\ font setups will break, because with the original mapping still in place, the engine will be attempting to insert unicode maths glyphs from a standard font.
+%
+% \begin{macro}{\use@mathgroup}
+% To overcome this, we patch \cs{use@mathgroup}, which is only used inside of commands
+% such as \cs{mathXYZ}, so this shouldn't have any side-effects.
+% Omit the test for math mode because this is only called \emph{inside} \cs{mathrm} or similar,
+% which already has a math mode check.
+% \begin{macrocode}
+\cs_set:Npn \use@mathgroup #1 #2

+ \@@_switchto_literal:
+ \@@_mathgroup_set:n {#2}
+ \@@_group_end:n
+ }
+% \end{macrocode}
+% \end{macro}
+%
+% In LaTeX maths, the command |\operator@font| is defined that switches to the |operator| mathgroup. The classic example is the |\sin| in |$\sin{x}$|; essentially we’re using |\mathrm| to typeset the upright symbols, but the syntax is |{\operator@font sin}|.
+% I thought that hooking into |\operator@font| would be hard because all other maths font selection in 2e uses |\mathrm{...}| style.
+% Then reading source2e a little more I stumbled upon \cs{@fontswitch}.
+% Reimplement that here to avoid \cs{bgroup}/\cs{egroup}.
