I am afraid it is a known issue. When using gst-remote (the scripts/
the Smalltalk In Smalltalk (STinST) parser is being used to parse your extension
and it doesn’t seem to handle instance variables.

With my time constraints I just maned to switch the order, load my code before
gst-remote is being used. :(

The STInST package is in packages/stinst/parser and based on the refactory
browser. With the there are some examples. I used VisualGST in
the past to debug it but then renamed the namespace so I would use a different
parser than VisualGST is using itself. There are also some testcases that could
be serve as an example.
