Since I feel in danger of being misquoted here (the stuff about Dr. Howland
is from Russ Urquhart, I think - definitely not me), can I restate my view:

[1] APL's array orientation means that a lot of the explicit code structuring
of scalar languages can be replaced by the implicit data structuring of APL.

[2] Many of the previously-suggested flow of control proposals for APL have
seemed to me to be inadequate; but Wilhoft's paper appears to introduce some
very attractive ideas. I look forward to any implementation of it, and reading
the other APL93 papers on this subject.

[3] I worry that improved APL capabilities in this area might lead to even
poorer coding techniques than are already common in the field.

[4] Bob Bernecky is absolutely correct in his statement that many real-life
problems, especially those that interact witht he real world, will benefit
from a more sophisticated flow of control mechanism.
