LaTeX offers the following way to write a cube root: $\sqrt[3]{x}$.  Is 
there a way to do this in ConTeXt other than the TeX way of $\root 3\of x$?

Also, Hans, if there isn't a direct way to do this, the following code is 
pretty much how LaTeX implements it, with an extra line at the top to make 
it work in ConTeXt.  Would it be reasonable to put something like this (or 
something that implements this syntax) in m-newmat?

    \let\sqrtsign=\sqrt
    \def\sqrt{\@ifnextchar[\@sqrt\sqrtsign}
    \def\@sqrt[#1]{\root #1\of}
