Comment (by rhaas):

 The problem with teaching tools that one dot might be in the variable name
 is that they then have to know all possible dotted parts. eg we generate
 all of these file names depending on how many processes are outputting,
 whether index files are used and what direction output is used:

 * grid.x.x.file_0.idx.h5
 * grid.x.x.idx.h5
 * grid.x.x.h5
 * grid.x.h5

 with all of x,y,z, xy,xz,yz, xyz for second "x". Things get further
 complicated by the fact the the old-style 3d hdf5 output does not put any
 indicator into the file name for what slice type it outputs, so grid.x.h5
 could be either grid::x and full 3d output or the x-axis slice of a
 variable grid.
