something

\ifdefined\t \else \unexpanded\def\t{\mathortext\text\mathtext} \fi
\ifdefined\w \else \unexpanded\def\w{\mathortext\word\mathword} \fi

\appendtoks
     \let\t\mathtext
     \let\w\mathword
\to \everymathematics

because sometimes a \t or \w is part of an expansion so we need it to be 
defined then (for instance, Alan loves to put lots of complex math in 
textext)
