    $\begingroup$ I have heard Mathematica being called a multi paradigm language. $\endgroup$ Commented Dec 30, 2013 at 10:08
  • $\begingroup$ +1 I believe that once you understand the Mathematica evaluation and the use of With you can do almost anything with Mathematica. $\endgroup$ Commented Dec 30, 2013 at 10:15
  • $\begingroup$ @JacobAkkerboom, I've heard the same, so I will add some notes to reach a wider audience. Thanks! $\endgroup$ Commented Dec 31, 2013 at 0:10

    $\begingroup$ An easy way to understand Mathematica's evaluation: consider a function/tree f[a,b]. Without any particular attribute for f the leafs/arguments will be evaluated before the parent f. With f having a HoldAll attribute you don't evaluate the leafs but go directly in the evaluation of f. a and b will be evaluated as soon as they are used in a function that doesn't hold again their evaluation. Example SetAttributes[f, HoldAll]; f[a_,b_]:= a Hold[b]; f[2^2,2^2] $\endgroup$ Commented Dec 23, 2014 at 20:38

    $\begingroup$ "Everything in Mathematica is an expression" - not Dataset, which has its own type system under the hood and doesn't work with external pattern matching and replacement. $\endgroup$ Commented Jul 1, 2015 at 18:29
