History
History • 1995 • Yukihiro Matsumoto (aka Matz) • Philosophy:
Designed for programmer productivity and fun.
History • Inspired by Perl, Smalltalk, Lisp, Python • “I
wanted a scripting language that was more powerful than Perl, and more object-oriented than Python. That's why I decided to design my own language.”

Strong typing
Duck typing • it walks like a duck; • it
talks like a duck; • it will probably be a duck.

BEHAVIOUR
