* "common_dtype" causes all the operands to be converted to
a common data type, with copying or buffering as necessary.
+ * "copy_if_overlap" causes the iterator to determine if read
+ operands have overlap with write operands (except if
+ the arrays are exactly the same), and make temporary copies
+ as necessary to avoid overlap. False positives (needless
+ copying) are possible in some cases.
* "delay_bufalloc" delays allocation of the buffers until
a reset() call is made. Allows "allocate" operands to
be initialized before their values are copied into the buffers.
