* op_type The type of the operation.
* op_opt Whether or not the op has been optimised by the
* peephole optimiser.
- * op_static Whether or not the op is statically defined.
- * This flag is used by the B::C compiler backend
- * and indicates that the op should not be freed.
*
* See the comments in S_clear_yystack() for more
* details on the following three flags:
-
+ *
* op_latefree tell op_free() to clear this op (and free any kids)
* but not yet deallocate the struct. This means that
* the op may be safely op_free()d multiple times
* op_latefreed an op_latefree op has been op_free()d
* op_attached this op (sub)tree has been attached to a CV
*
- * op_spare two spare bits!
+ * op_spare three spare bits!
* op_flags Flags common to all operations. See OPf_* below.
* op_private Flags peculiar to a particular operation (BUT,
* by default, set to the number of children until
* which may or may not check number of children).
