Overview

Checks for the use of ‘I18n.locale=` method.

The ‘locale` attribute persists for the rest of the Ruby runtime, potentially causing unexpected behavior at a later time. Using `I18n.with_locale` ensures the code passed in the block is the only place `I18n.locale` is affected. It eliminates the possibility of a `locale` sticking around longer than intended.

Examples:

# bad
I18n.locale = :fr

# good
I18n.with_locale(:fr) do
end
