I second this. What about the following:

                        {<math character class>}



the math category would always be \mathalpha (is this reasonable?)

\CYRA should then work in text and math mode...this is more like an alias
for a letter than a symbolic name IMHO.

LaTeX does this implicitly: you have a \DeclareMathSymbol{a}... but no
corresponding sequence for text mode!
