That sound nice, but nobody follows those commandments to the
letter. Really, nobody does.

A more practical commandment is​:

  Thou shalt learn the rules of precedence. You're going to need
  to know them eventually, so you might as well learn them now.

That would make a lot of sense if the rules and notations were absolutely
uniform across all languages, and if the user was a heavy-duty Perl
programmer. Since neither of those is universally true, a many practical
people probably ought to find some comfortable middle ground.
