Wx::perl::datawalker implements a wx::frame subclass that shows a relatively simple perl data structure browser. after opening such a frame and supplying it with a reference to an essentially arbitrary data structure, you can visually browse it by double-clicking references.

so far, there is no tree view but only a display of the current level of the data structure. you can traverse back up the structure with a back button.

optionally, wx::perl::datawalker displays the (approximate!) size of the data structure using devel::size.
