We should DROP \m{} (in favor of \math{}) as this is really useless. I
suppose that in the beginning (and according to Aditya's blog), this
was some attempt to be as short as $...$, well only two characters
longer. Since no one in his or her right mind would regularly use
\m{...} in favor to $...$, as Aditya himself suggests above, it is
redundant. Indeed, \math{...}, context.math(¨..."), \mathematics{...}
and context.mathematics("...") have their utility. See also below.

Hans, you forgot: ¥x^2¥, ₽x^2₽, ₱x^2₱, ₹x^2₹, ...
Besides, U+0024 comes from ASCII and all programmers know that it is a
perfectly valid and useful character.

Too bad Knuth did not choose ¡x^2!

This is a good case for \math[i:tight]{x^2}

The \math or \mathematics variant should work in all such cases.
