diff Python/ceval.c @ 27201:dc6fb8a6af3d legacy-trunk
As discussed on python-dev, removed from DUP_TOPX support for the
parameter being either four or five. Currently, compile.c does not
generate calls with a parameter higher than three.
May have to be reverted if the second alpha or beta shakes out some
other tool generating this op code with a parameter of four or five.
