Hi,
I was playing around a bit with js shell... I noticed this:
js> throw {}
can't convert undefined to an integer

Is this the expected result? I was expecting something along the lines 
of "uncaught exception: object", maybe even "uncaught exception: {}"


A second issue:
js> throw { toString: function() { return "foo" } }
can't convert undefined to an integer

Why did this not print "uncaught exception: foo"?

Compare:
js> throw 42
uncaught exception: 42
js> throw "foo"
uncaught exception: foo

Throwing {} does seem to work:
js> uneval({});
({})
js>  try { throw {}; } catch (e) {  print(uneval(e)); }
({})


This is with latest CVS, Linux, "make -f Makefile.ref".
