Does Ruby offer an equivalent of Perl's use strict?
perl, ruby
Solution
The strict pragma does three things in Perl. Two of the items are to forbid the use of symbolic references and "barewords." Ruby doesn't support these features, so it's not an issue.
The other feature of the strict pragma is to avoid creating random global variables every time one is mentioned. In Ruby, globals look different from other variables (the leading $), so this is not really a problem. Local variables need to be assigned to before use, since that's Ruby's method of declaration. That solves the same problem the strict pragma handles for Perl.

Problem
I mean, there is no `my` in Ruby. I found `use strict` in Perl to provide very good anti-typo protection.
