The gem did_you_mean uses a class instance variable that does not work with Ractor.

$ RUBYOPT='--disable-did_you_mean' ruby -W0 -e 'Ractor.new{ begin ; nil + 42; rescue Exception => e; e.to_s end}.take'
# => prints nothing (ok)

$ ruby -W0 -e 'Ractor.new{ begin ; nil + 42; rescue Exception => e; e.to_s end}.take'
# Prints

Typo: I meant a class variable, not a class instance variable.
