   This macro is intended to have two arguments,
   the name of the string to define and its content.
   Currently, it is ignored including its arguments,

   Pops a result off the stack of conditional evaluations pushed by
   .Sx \&ie
   and uses it as its conditional.
   If no stack entries are present (e.g., due to no prior
   .Sx \&ie
   calls)
   then false is assumed.
   The syntax of this macro is similar to
   .Sx \&if
   except that the conditional is missing.
