Would you mind weaving it into my code so I can see for myself? (Note: The following provides answers already given in essence by LanX, but it at least also provides an example of sorts and so may be helpful.) ... how would I use [data dumper] to see the data and the structure of $ua and $res? Untested: Please see Data::Dumper. (Note: Be prepared for a lot of data to be dumped from some object references!) Also a point of confusion: is It is not. The expression $ua->show_progress invokes (without any arguments) the method show_progress() in the class (or a superclass) of which $ua is an object reference. The expression $$ua{show_progress} attempts to access the value of the 'show_progress' key in the anonymous hash to which $ua is presumed to be a reference; it is an error if $ua is not a hash reference. This expression is the same as the form $ua->{show_progress} which is preferred (properly, IMHO). I'm using Data::Dump in this example instead of Data::Dumper because I like its output formatting better; the latter is core, the former is not. Give a man a fish: <%-{-{-{-<
