you've seen the Cookbook? [1]  see the section on inline collections [2] 
for examples.  yikes, i just noticed this is missing from the docs. [3] 
  i will fix.

YAML::load and YAML::dump both accept IO objects of any kind:

   obj = YAML::load( File.open( "filename" ) )

to dump:

   YAML::dump( obj, File.open( "filename2" ) )

follows Marshal's API.

please ask all you like, i'm interested to know where documentation is 
lacking (working on ri docs today) and what is tripping up any of you 
from slathering your scripts in YAML.
