%D This is a variant on radicals but in the end it was better to just define a new
%D environment for this. This is because we don't have the rule and we want a
%D different control over the spacing. We also don't want the degree.

% Todo: also add the mp plugin here but that more fun stuff for later (when we pick
% up school math).
