My first question is, how do I load correctly OMeta2 into Squeak
5.3? I'm loading it using monticello browser and several errors
first one is syntax error that I ignore. I assume it's related
to that Ometa extends smalltalk syntax with its own one.
second one is: MessageNotUnderstood:UndefinedObject>>isOMeta2Rule:
.I choose to just implement one, in Object class, that returns
always true value.
The third one is MessageNotUnderstood:
OMeta2Compiler>>parseCue:noPattern:ifFail: . I tried
to debug it and it seems it's sent to parser, but parser
understands such message or am I reading it wrong? Attempting to
implement it in Compiler class instance side, results in
infinite loop (image freeze).
Is there some way to load it, or something is broken in newer

website + installed Babelsberg package.
My second question is, how can I implement infinite 2D world/pane
where I can scroll/use mouse "click and drag" to navigate? What
