Subject: Re: [PATCH] coccinelle: assign signed result to unsigned variable

To collect function calls that have a return value of a given type t, it
should be sufficient to do the following:

@@
t e;
identifier f;
@@

f(...)@e

The @e notation reaches upwards to match the innermost enclosing term of
the right kind (here expression).

t can of course be arbitrarily complicated.
