I find it understandable that implementors want to have the symbol map
at a fixed location, as this saves at least one indirect reference per
symbol access.  But nevertheless it should be possible to increase this
size dynamically, even if this means moving the rest of the WS and
shuffling around a lot of pointers.  Less work than a typical )COPY must
perform.  This seems to be one the few non-dynamic features of APL left
from the past, like the traditional bracket notation for indexing, which
fixes the rank of an object at programming time.
