/**************** Specializations of __gmp_expr ****************/
/* The eval() method of __gmp_expr<T, U> evaluates the corresponding
   expression assigning the result to its argument, which is either an
   mpz_t, mpq_t, or mpf_t -- this depends on the T argument, which is
   either __gmpz_value, __gmpq_value, or __gmpf_value, respectively.
   Compound expressions are evaluated recursively (temporaries are created
   to hold intermediate values), while for simple expressions the eval()
   method of the appropriate function object (available as the Op argument
   of either __gmp_unary_expr<T, Op> or __gmp_binary_expr<T, U, Op>) is

/**************** Macros for defining functions ****************/
/* Results of operators and functions are __gmp_expr<T, U> objects.
   T determines the numerical type of the expression: it can be either
   __gmpz_value, __gmpq_value, or __gmpf_value.
   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.
   When the arguments of a binary expression have different numerical
   types, __gmp_resolve_expr is used to determine the "larger" type.
   Actual evaluation of a __gmp_expr<T, U> object is done when it gets
   assigned to an mp[zqf]_class: this is done by calling its eval()
   method. */
