Not sure whether it is ironic or not when you write "will make things
interesting" ? :-)
The already existing syntax coloring of clojuredev (with rainbow
parens enabled) does just that, reparsing the whole file everytime.
And I've found it useful to see that what I really know is a top level
form does not have the right color. It helps identify where the
problem begins ...

More homework ! :-) Thanks for the pointer,
