An argument might be that doing so you enlarge the set of legal yet
non-compilable programs. Ideally, each legal program should be compilable.
Furthermore, a program successfully compiled by the compiler X on the
machine M, should also be compilable by the compiler Y on N.
Theoretically, limiting the identifier length (and everything else from
subprogram body size to record members number) makes sense. The actual
problem is IMO that any choice of such a limit would be arbitrary, and
there are far too many such limits to define.
