IMO, the *real* trick is to admit that the meta-language is also
someone's object language, so it's better to go with something better
than bold...  I went with underlines.

(The problem there is that a simple underline will consider all of its
characters, which means that if you use that on disjoint parts you get
lines at different heights.  Then I discovered \underbar, and use it
like this:
  \newcommand{\Q}[1]{\ifmmode \underbar{\ensuremath{#1}}%
                     \else    \underbar{#1}%
                     \fi}
)
