improper output:

expected output:

— !ruby/object:MailTruck

route:

Is this an issue with cmd.exe or irb?  
Anyone know how to fix this situation?

neither. irb was showing you the return value of your function call  
effectively, p whatever

try:  
puts(YAML::dump(m))

Meh. So gruesomely verbose 😜 Quoting yaml.rb:

```
#
# ryan:: You know how Kernel.p is a really convenient way to dump 

```

ruby  
# structures? The only downside is that it’s not as legible  
as  
# YAML.  
#  
# \_why:: (listening)  
#  
# ryan:: I know you don’t want to urinate all over your users’  
namespaces.  
# But, on the other hand, convenience of dumping for  
debugging is,  
# IMO, a big YAML use case.  
#  
# \_why:: Go nuts! Have a pony parade!  
#  
# ryan:: Either way, I certainly will have a pony parade.  
#

(Definition of Kernel#y follows.)

Use:  
y m
