<amalloy> (doc update-proxy)
<lazybot> => "([proxy mappings]); Takes a proxy instance and a map of
strings (which must correspond to methods of the proxy
superclass/superinterfaces) to fns (which must take arguments matching
the corresponding method, plus an additional (explicit) first arg
corresponding to this, and updates (via assoc) the proxy's fn map. nil
can be passed instead of a fn, in which case the corresponding method
will revert to the default behavior. Note that this function can be
used to update the behavior of an existing instance without changing
its identity."
