The problem here is the restructuring of the swig interface; the
rshift operator on FunctionPlotData is defined before the definition
of FunctionPlotData. This causes swig to ignore the rshift (and
lshift) operator for FunctionPlotData, and hence the lines

f = File(filename)
f >> FunctionPlotData()

fails.
