$$ allows on to put a variable name in another variable and use it. I
would like a function, usable only in UDFs, that would return the actual
variable name associated with a function argument. This is,
approximately, the inverse of $$. One can achieve this by requiring the
user to to send all arguments as strings and using $$ throughout, but
that puts an undue burden on the function user.
