That looks very nice and I would find it nice, too.

(I've been using YAML.load(File.read(filename)) for this which isn't all 
that comfortable...)



Oh, and here's something I find quite confusing about yaml.rb:

It's possible to do YAML.load("- foo"), but YAML.load("[foo]") produces 
a parse error. (YAML.load("---\n[foo]") also works.)
