Simple qualified subfield names are in V5R1.  That is, code keyword
QUALIFIED on a data structure definition, and the subfields are
referred to as "DSNAME.SUBF".  "Simple" means just that, with no
whitespace allowed between the two names and the dot.

A related enhancement that you should get to know very well as you
learn V5R1 is keyword LIKEDS.  A data structure or procedure
parameter defined with LIKEDS inherits all the subfields of the
other data structure.  So you can define data structure A as
qualified with subfield X and data structure B as LIKEDS(A) with no
subfields, and you can refer to subfields A.X and B.X.  The
advantages of LIKEDS used with procedure parameters should be
obvious.

I agree that some sort of packaging mechanism for modules would be
a good thing to help manage name conflicts.
