; is used as the composition operator in "diagrammatic order" (Category (mathematics) - Wikipedia).  Although we can't use the normal semicolon as a binary operator in Jul...

Would it make sense to define the ^ operator for iterated functions? Something like:  ^(f::Function, n::Integer) = ∘(fill(f,n)...)  Then we can do things like  typeof(1.0) |> supertype^3  Instead of  typeof(1.0) |> supertype |> supertype |> supertype  A possible downside: people might expect (sin^2)(x) to mean sin(x)^2 instead of sin(sin(x)) (although they should not IMO 😉).

A comprehensive introduction to optimization with a focus on practical algorithms for the design of engineering systems.
               This book offers a comprehensive introduction to optimization with a focus on practical algorithms. The book approaches optimization from an engineering perspective, where the objective is to design a system that optimizes a set of metrics subject to constraints. Readers will learn about computational approaches for a range of challenges, including searching high-dimensional spaces, handling problems where there are multiple competing objectives, and accommodating uncertainty in the metrics. Figures, examples, and exercises convey the intuition behind the mathematical approaches. The text provides concrete implementations in the Julia programming language. Topics covered include derivatives and their generalization to multiple dimensions; local descent and first- and second-order methods that inform local descent; stochastic methods, which introduce randomness into the optimization…
