Or use some more catcode trickery to ensure that - is equivalent to
\mathematics{-} ;)

Latex is not all that bad :) It has \textsuperscript and
\textsubscript (though most people still write 29$^\text{th}$ June
rather than 29\textsuperscipt{th} June)

The wrapping in \hbox is not that bad. A lot of math trickery happens
inside a \hbox. The example on contextgarden
(http://wiki.contextgarden.net/Bold_Math) is not too different from
how bm.sty implements bold symbols in latex (which is the best bold
math implementation in latex, AIUI). However, the \boldmath definition
on contextgarden lacks
1. Use of pmb (poor man's bold) when a true bold character is not
present. \boldsymbol{\sum} does not work.
2. Does not take care of the math spacing
\formula{ a \boldsymbol{=} a } does not look correct.
3. Does not take care of delimiters
\formula { \boldsymbol{\left(}\frac 1n\right)} does not work.
4. bm.sty goes into some trouble to define bold accents. So
\bm{\hat}{a} produces a bold accent over a non-bold a. (I can not
understand why would someone ever use that).
Hans, why is [boldmath] not defined by default in all the typescripts?

It can be used everywhere. For example
\def\myrmbf{\boldmath\rm\bf}
{\myrmbf How to loose a guy in $10$ days}
It will be nice if one could write
\def\mybf{\boldmath\previousfont\bf}
Maybe what is needed is a \beforemathswitch token set. Then one could
do
\appendtoks \boldmath to \beforemathswitch
