it.grypho.scala.leonardo.scalar._Derivative
AST node for symbolic differentiation: derive(e, v) in the grammar.
eval delegates to derive , and guards against the fixpoint case where derive returns this (would loop forever): if the algorithm cannot reduce, stays symbolic.
Value parameters
e
the expression to differentiate
v
the differentiation variable (binder -- excluded from children)
