I have a love-hate relationship with columns. On the one hand, they are
very concise. Concise is nice when it comes to writing, but not
necessarily when it comes to reading (like APL). In particular, imagine
F specifications. There's a lot of information packed in to relatively
few (common) columns. Pretty easy to write, not so easy to read.

I myself have mixed feelings about reading columnar calculations. On
the one hand, it was pretty easy to have all the result fields lined up
like that. On the other, that was because we couldn't use expressions,
so it took multiple lines of code to do anything more complex than ADD 1
X :-)

The good news is that it's not an exclusive-or situation. Those who
find a use for columns can use them even in and among fully free lines
of code.
