ERROR: UndefVarError: filename not defined

The filename in two libraries have different signatures. They should not have any clash I suppose? Why couldn’t they coexist?

I’m not sure it can be avoided. There are plenty of packages that will have similar but distinct capabilities and the terms are too common to avoid. If I’m using two different plotting packages because they are better at different things then I expect each to have a plot function. In that case I would then have to distinguish between the two.

PyPlot.plot() vs Gadfly.plot()

Have you tried FileIO.filename or HDF5.filename?

Yes I know FileIO.filename will work. I expect the system accept possible ambiguities, and show error only when there are ambiguous calls in runtime.
