Anthony,

Try compiling the following method in any class:

foo
  1 = 1 ifTrue: [2]

I get the error 'positive if jumps only'.

Now, don't ask *why* someone would write such a method (anything you do to
make it useful gets rid of the error) but this is a minimal example of an
actual method in Comanche that has the same problem, so I thought I'd
point it out.
