[BUG] Aliasing :lambda


(Florian Gross) #1

Moin!

I just found this crash – it might not make much sense to make :lambda
a module_function and the code was in fact broken, but this should IMHO
be fixed anyway.

C:\dev\ruby>ruby -e “Module.new { module_function :lambda }”
-e:1: [BUG] undefined method `lambda’; can’t happen
ruby 1.8.1 (2004-01-27) [i386-mswin32]

This application has requested the Runtime to terminate it in an unusual
way.
Please contact the application’s support team for more information.

Module.new { module_function :lambda }
-:1: [BUG] undefined method `lambda’; can’t happen
ruby 1.8.0 (2003-08-04) [i686-linux]


I send this to both comp.lang.ruby and matz, because the gateway seems
to be quite instable at the moment. I hope this message doesn’t get lost
in total nirvana.

Regards,
Florian Gross

D’uh, the topic should be “[BUG] module_functioning :lambda”.

Thank you for the report.
