Infinite recursion in slotSummary / asString if a list() has a reference to higher object

[dennisferron]

Hitting an object containing the value "list(self)" causes an infinite recursion in slotSummary (and therefore asString, writeln and the REPL). Perhaps related to issue #36?

This surprisingly short line will hose the REPL:
Io> list(Lobby)

Or try this in a script file or in the REPL:

Io> a := Object clone do( init := method( newSlot("die", list() append(self) ) )
... )
==> Object_0x232ab70:
init = method(...)

Io> writeln(a clone)
^C
IOVM:
Received signal. Setting interrupt flag.

Yes, this looks like a duplicate of #36 so I'm closing this one.
