You don't have to, when you trust other programmers, and you have time
to run test suite before deploying the software. It gives you new
possibility, possibility to do many good things, along with a few
dangerous things. Ruby makes you free. You are even free to shoot
your own foot.

Often there are cases where we can not trust each other for various
reasons: immature programmers, discommunication between team members,
etc. Under such circumstance, it is dangerous and lead to bad
practices. Don't use Ruby for such cases. It's no fun.

Do you consider Ruby a good language for teaching people that haven't
programmed yet? Just wondering.

Sorry for answering the question addressed not to me,
but I'm an aged professional programmer who programmed in many languages
and for a long time was a lecturer and trainer of OOP.
Compared to other programming languages Ruby has many attracting
features. It is clear in understanding, pure OO, lightweight and
elegant, pragmatic and powerful, cross-platform, was deriveded from good
parent languages, absorbed modern programming ideas, supports different
programming paradigms.
So Ruby is almost ideally suitable for students and teachers, and I
strongly recommend for beginner programmers to start with Ruby.

I personally consider teaching programming in any language without a
REPL as Cruel and Unusual (tm) torture. Compiler-wrestling is a skill of
much value, but should be kept out of introductory courses and put into
language-specific seminars, IMO.

Disclaimer: That's from the position of a "victim" of having an
introductory course in (Borland Turbo) C, not an actual instructor.

What is a REPL?

Read-eval-print-loop. For example, irb.
