running ala Perl's strict

[David Garamond]

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?

No, though I wish there were. You can hack it with a thread that reads
from standard error and looks for warnings.
