Thanks Doru, Pharo environment, specially GT Tools and Roassal have been really empowering. Next step is to explore GT-Spec integration for a more familiar and versatile interface.

Looks interesting ! Did you have a look to Jupyter notebook ? https://jupyter.org/ This could be nice if we could have a Pharo support for this (already supported by other languages like R, Python, Scala, etc ...).
