Syntax

it.grypho.scala.leonardo.scalar.Syntax
object Syntax

Optional method-call syntax for the scalar algorithms.

Lets callers write e.simplify() instead of simplify(e). Kept in an object (and out of the _Expression trait) so core depends on no domain and the method names do not collide with the top-level package functions they forward to. Opt in with import scalar.Syntax.*.
