I can see arguments either way.

Take the very simple case
      x = 5
      plot sin(x)/x
Do you expect the plot key to show  "sin(x)/x" or "-0.19178"?

Or, closer to your example,
      Data(year) = "dataset-".date.".dat"
      plot Data(1881)
Do you expect the plot key to show "dataset-1881.dat" or "Data(1881)"?
