comment What are the most common pitfalls awaiting new users?
Holding evaluation allows to destructure arguments and modify them before evaluation SetAttributes[f, HoldFirst]; f[h_[b_]]:={h,b}; f[g[2]]

comment What are the most common pitfalls awaiting new users?
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]
