Comment (by robertwb):
:)
The Cython code looks plenty clean though.
{{{
#define __Pyx_PyBool_FromLong(b) ((b) ? (Py_INCREF(Py_True), Py_True) :
(Py_INCREF(Py_False), Py_False))
...
static PyObject
*__pyx_pf_4sage_5rings_7integer_7Integer_is_perfect_power(PyObject
*__pyx_v_self, PyObject *unused) {
PyObject *__pyx_r;
PyObject *__pyx_1 = 0;
/* "/Users/robert/sage/sage-3.1.3/devel/sage-
main/sage/rings/integer.pyx":3002
* False
* """
* return mpz_perfect_power_p(self.value) #
<<<<<<<<<<<<<<
*
* def jacobi(self, b):
*/
__pyx_1 = __Pyx_PyBool_FromLong(mpz_perfect_power_p(((struct
__pyx_obj_4sage_5rings_7integer_Integer *)__pyx_v_self)->value)); if
(unlikely(!__pyx_1)) {__pyx_filename = __pyx_f[0]; __pyx_lineno = 3002;
__pyx_clineno = __LINE__; goto __pyx_L1_error;}
__pyx_r = __pyx_1;
__pyx_1 = 0;
goto __pyx_L0;
__pyx_r = Py_None; Py_INCREF(Py_None);
goto __pyx_L0;
__pyx_L1_error:;
Py_XDECREF(__pyx_1);
__Pyx_AddTraceback("sage.rings.integer.Integer.is_perfect_power");
__pyx_r = NULL;
__pyx_L0:;
return __pyx_r;
}
}}}
(Note that much of that gets optimized away at compile time, for example
the error branch is never taken).
