I really love the use of fuel to serialize errors on the build server:
-------------------------------------------------------------------------
[
� �"some code causing an error"
� � Error signal
] on: Error do: [ :error |
� � FLSerializer serialize: error toFileNamed: 'error.fuel' ]
-------------------------------------------------------------------------
Then in a new image open a debugger on the serialized error:
-------------------------------------------------------------------------
error := FLMaterializer materializeFromFileNamed: 'error.fuel'.
error debug.
