rubyx/test/fragments/test_while_fibo.rb
Torsten Ruger f4a4ccb98e several larger changes came together, bit of cleaning too
- all code must be in functions (which must be in classes).
— changes a fair few tests
— also changes api, as method is not recursive, not passed around
- all state in instance vars in compiler (no accessors)
- class is another such variable, surely more coming
all green again
