Subject: running ala Perl's strict

With -w (verbose mode), Ruby can print compilation warnings, like 
uninitialized instance variables.

  $ ruby -we 'p @a'
  -e:1: warning: instance variable @a not initialized

Is there a mode (ala Perl's strict or something similar) that makes Ruby 
raises errors for compilation warnings?
