Patches are always welcome. :) The call line is evaluated by first expanding itself into a full code block, so perhaps you could add functionality to C-c C-v v so that it will expand this ephemeral code block. Additionally it may be easy to update C-c C-v I so that it works on call lines, which may provide the information you're after.
