[texhax] How equate two macros so that when you redefine one, the other also gets redefined.

have an alias macro (say \you) for \me such that whenever you redefine 
\you, then \me also gets redefined.

The simplest solution is \def\me{\you}; then \me will always expand to
\you, although technically they don't have the same definition.
Otherwise you have to create a macro to redefine \you, so that \me gets
redefined too:

\long\def\defyou#1#{%
   \DEFYOU{#1}%
   }
\long\def\DEFYOU#1#2{%
   \def\you#1{#2}%
   \let\me\you
   }


Best,
Paul
