+/* Some notes on Eigen's static assertion mechanism:
+ *
+ * - in EIGEN_STATIC_ASSERT(CONDITION,MSG) the parameter CONDITION must be a compile time boolean
+ * expression, and MSG an enum listed in struct ei_static_assert<true>
+ *
+ * - define EIGEN_NO_STATIC_ASSERT to disable them (and save compilation time)
+ * in that case, the static assertion is converted to the following runtime assert:
+ * ei_assert(CONDITION && "MSG")
+ *
+ * - currently EIGEN_STATIC_ASSERT can only be used in function scope
