It would require special tailored code for each type. (normal
arrays, open
arrays, dynarrays, pchars (length) etc etc)
All the arrays would be handled the same. The compiler can just
generate low() and high() nodes, and those will automatically do the
right thing.
Since a pchar is not an array but a pointer to a (possibly null-
terminated) array, whether or not that construct supports pchars
would be a separate decision.
