I want to write a macro with 2 arguments, the first one being a single
characters, which makes #1 active and defines it as #2. I tried    

    \def\makeactive#1#2{\catcode`\#1=\active \let#1{#2}}

but it doesn't work. Does anybody have an idea ? Note that the
definition should be local to the group in which \makeactive occurs.
