That's all well and good, but if the percentage of those kinds of errors
is absurdly low in your application to begin with, it doesn't buy you
very much. Furthermore, if the benefits provided by static typing (and I
don't dispute that there are benefits) outweigh the costs (which can be
considerable in some languages), then it can be a net loosing
proposition.
I'm actually somewhat ambivalent about static typing. I find it to be
very useful in a language like C++ where the syntax is complex and the
function invocation syntax makes it easy to transpose (or even leave
out) arguments. Languages that have lots of rigid rules provide lots of
opportunities to break them. I have never felt the need for a static
typing system in Smalltalk (except maybe to provide better compile-time
optimizations). The syntax is simple, the rules are few, and I just
don't find myself making the same kinds of mistakes that are made all
too frequently in other languages. I imagine that if you were to ask
other folks who have programmed extensively in statically types
languages (like C++) as well as Smalltalk, I suspect that you would get
the same result.

The largest Smalltalk project I worked on was well over a million lines
of code and had 10-30 people working on it at any one time. The largest
Smalltalk project that I worked on by myself had over 100,000 lines of
code in it. I have personally written over 400,000 lines of commercial
Smalltalk code (ranging from shrink-wrapped apps to mission critical MIS
apps).
Why do you ask?
