00016 # Replication was introduced in issue #160 (original trac).

00018 # It turns out the Python compiler will automatically expand sequence*integerconstant
00019 # When integerconstant is <= 20.  So these tests use 30 so that BINARY_MULTIPLY
00020 # is exercised and the replication functions are called.
