I was depending less and less on the type system for safety. My unit tests were preventing me from making type errors. The more I depended upon the unit tests, the less I depended upon the type safety of Java or C++ (my languages of choice).
[...]So I tried writing some applications in Python, and then Ruby [...]. I was not entirely surprised when I found that type issues simply never arose. My unit tests kept my code on the straight and narrow. I simply didn't need the static type checking that I had depended upon for so many years.

We translated [to Python] a simple IdentityMap class that I had written in Java. It was interesting to me that we did an awful lot of deleting: semi-colons, the curly braces, the primitive-wrapping objects, the variable types. Oooh, there ain't nothin' like deletin' stuff!I think I glimpsed something today. All that rigid type safety and data hiding is like wearing army boots on the beach: nothing can bite your toes, but golly don't it feel good to just toss 'em and run barefoot.
