Hrm, okay, but that site seems to suggest that this line shouldn't work:
"The following code snippet almost works, but not quite...
class MyClass
def initialize(options = {:name => 'unknown', :size => 0})"
That function definition looks exactly like what we see here:
def execute(command, arguments = {:failonfail => true, :combine => true})
why do we expect it to work here?
