Subject: Simple marshaller "style" question
Content-Type: text/plain; charset=us-ascii; format=flowed

So, Jacques' "pointer" to GtkSignal.marshal2 was all that was needed 
to get me a working event system for my LablGTK Scintilla wrapper 
(BTW, is this a binding, a wrapper, or something else?).

However, just using e.g. marshal2 int pointer "sci-notify" puts the 
callback in the position of needing to transform  (into an OCaml 
record) the Gpointer.boxed option that the pointer is marshalled as... 
which is certainly usable, but not ideal.

OTOH, doing my own complete version of marshal2 just so I can call my 
"ml_..." function on "arg2" at the very end seems a bit inelegant, but 
that is what I am doing for the time being.

So, given that marshal2 or whatever I do is being used via a "partial 
application" (I think that is what you types call it) that goes into 
the GtkSignal.t record, is there a more "HOF style" way of reusing 
marshal2 but processing the argument(s) *before* the callback is 
invoked, or is the custom version of marshal2 the best I can do?
