Looks like it.

Yep, they are! I had the "usual" counter counting to 6, then I changed
the ++ and -- methods to perform the calculations for the Collatz sequence
(n -> n/2 on --, n -> 3n+1 on ++) and ran:

gst-remote --eval "Smalltalk removeFeature: #App. PackageLoader fileInPackage: 
'App'" 

and, big cheer, -- led me to 3, then ++ gave me a 10.
