I remember a family of languages where (func x y) is the only syntax : Lisp. :)

I tend to agree when one says custom operators are evil. However, when
the default syntax uses operators, the custom ones are a net win : a
wise programmer will use their semantic load carefully (big nums, for
example), and sparsely, so the code is more readable.  An unwise
programmer will make the code unreadable anyway, regardless of the
operators.
