+Subject: [PATCH] Fix typing of array.typecodes for Python 3.15
+
+Python 3.15 changed array.typecodes from str to tuple to support
+type codes longer than 1 character (Zf and Zd).
+See https://github.com/python/cpython/issues/148675
+
+Pythran's fill_constants_types() uses type() introspection on live
+Python constants to set signatures, which now produces tuple instead
+of str. Meanwhile, the explicit ConstantIntr(signature=str) was
+silently ignored because ConstantIntr.__init__ never stored it.
+
+Fix ConstantIntr to preserve an explicitly provided signature, and
+skip introspection in fill_constants_types when one is already set.
+
+Without the fix, pytest pythran/tests/test_array.py -k test_typecodes
+fails with:
+
+        else:
+>           raise NotImplementedError(t)
+E           NotImplementedError: <class 'tuple'>
+
+pythran/types/tog.py:480: NotImplementedError
