Ah, yes, the HDF5 library won't do that. You could "fake" it by laying
out your struct in memory such that 'a_name' and 'b_name' are next to each
other in memory and could be read in as separate fields and then treated by the
application as the way you would like.

Not currently, although we've given the idea some thought.
