Silent failure when your yaml is bad can be a problem.  Here's a  
useful one liner that will pass silently or fail noisily.

perl -MYAML=LoadFile -e 'LoadFile $ARGV[0]'

also consider using .conf instead, it's less easy to get wrong.  Once  
you've got your app config working try this and swap out myapp.yml  
for myapp.conf:

perl -Ilib -e 'use MyApp; use Config::General; Config::General->new- 
 >save_file("myapp.conf", MyApp->config);'

There's probably some cruft in the .conf file you need to remove, but  
it's still less painful than yaml imo.
