static-typing

I've been using python for a few days now and I think I understand the difference between dynamic and static typing. What I don't understand is why it's useful. I keep hearing about its "flexibility" but it seems like it just moves a bunch of compile time checks to runtime, which means more unit tests. This seems like an awfully big tradeoff to make for small advantages like readability and "flexibility".

Can someone provide me with a real world example where dynamic typing allows me to do something I can't do with static typing?

SQLite3's dynamic typing

as seen on Stack Overflow - Search for 'Stack Overflow'
SQLite3 uses dynamic typing rather than static typing, in contrast to other flavors of SQL. The SQLite website reads: Most SQL database engines (every SQL database engine other than SQLite, as far as we know) uses static, rigid typing. With static typing, the datatype of a value is determined… >>> More

In my current job I'm building a suite of Perl scripts that depend heavily on objects.

Worse, they don't like reading documentation… >>> More
Static Typing and Writing a Simple Matrix Library

Aye it's been done a million times before, but damnit I want to do it again. I'm writing a simple Matrix Library for C++ with the intention of doing it right. I've come across something that's fairly obvious in mathematics, but not so obvious to a strongly typed system -- the fact that a 1x1 matrix… >>> More
