I would like to know how I can learn to write a complicated command with syntax like the one below. I might know each one separately, but I can not combine them or know the pattern which works for example where to apply @*, MatchQ[{(a_) ..}] or @*MatchQ[{(a_) ..}] @*.

Select[Not @* MatchQ[{(a_) ..}] @* Differences] @ test

@* means composition, while @ is shorthand for Prefix. f@x is just f[x], while (f@*g)[x] is f[g[x]] – flinty Jun 05 '20 at 18:14

Have you seen What the @#%^&*?! do all those funny signs mean? by Michael E2? – user1066 Jun 05 '20 at 18:22

Build the solution up step-by-step in separate cells so you can examine the intermediate results. After each step and the sequence of steps is working correctly, start combining the steps one at a time until you finally have the one-line solution. After you have done this several times you will be able to skip several or all of the intermediate steps. – Bob Hanlon Jun 05 '20 at 18:27
