/**************** Macros for defining functions ****************/
/* Results of operators and functions are instances of __gmp_expr<T, U>.
   T determines the numerical type of the expression: it can be either
   mpz_t, mpq_t, or mpf_t.  When the arguments of a binary
   expression have different numerical types, __gmp_resolve_expr is used
   to determine the "larger" type.
   U is either __gmp_unary_expr<V, Op> or __gmp_binary_expr<V, W, Op>,
   where V and W are the arguments' types -- they can in turn be
   expressions, thus allowing to build compound expressions to any
   degree of complexity.
   Op is a function object that must have an eval() method accepting
   appropriate arguments.
   Actual evaluation of a __gmp_expr<T, U> object is done when it gets
   assigned to an mp*_class ("lazy" evaluation): this is done by calling
   its eval() method. */
