Whoa, forget that. I've not had enough coffee today -- precedence does
the right thing.
But this method *is* to blame. Copy the block and replace self with -1
and arg with 1 and print it: answer -1.
How about this instead:
<primitive: 17>
self < 0 ifTrue: [^0 - (self negated bitShift: arg)].
^ super bitShift: arg
which seems to produce the right answers across a range of values.
