Pardon me for the language, I’d prefer to always try to set a better tone, a better conversational context, with waterfalls and the spirit herb growing along a stream. Yellow butterflies, of course. They’re Butter-flies. 🦋 darn.

I should correct this model I’ve proposed. Functions don’t walk an ASTFormulaTree, The Function's represented by the ASTFormulaTree and what’s walked is the input sets, double-D down the tree, transforming its values under send. Or something. I love design! Bread and Butter, architecture meets running implementation meets testing. It’s Scupturing.
