user defined procs are broken either way - at present, they can't take 
expressions are parameters:

q=p(3) correctly outputs a 3 in something like this:

  type file {};

  (file i) p(int n) {
    app {
      echo n stdout=@filename(i);
    }
  }

  file q <"volume.blah">;

  q=p(3);

but saying q=p(1+2) breaks with this:

Incompatible argument type for var: expected handle; got java.lang.Double. 
Offending argument: 3.0

for pretty much the same reason - its expecting a wrapped value but 
expression evaluation is providing an unwrapped value.

bleugh.
