Feature #5029: accept multiple args in Kernel#warn(), like puts()

• Status: Closed

[sunaku (Suraj Kurapati)]

Hello,

Please make Kernel#warn() like Kernel#puts():

• Accept multiple arguments.
• Print them separated by newline.

This will allow me to warn exceptions easily:

begin
...
rescue => error
warn error.inspect, error.backtrace
end

Instead of the current way, of having to write:

begin
...
rescue => error
warn error.inspect
warn error.backtrace.join("\n")
end

Thanks for your consideration.
