Suggestion: require parenthesis where operator precedence is non-standard

I noticed that the order of precedence for operators doesn't exactly conform to the guidelines that the rest of language follows: while in most places the compiler requires the programmer to be explicit (e.g. `pack` comments), precedence of operators is a (arbitrary?) choice of the compiler that will still confuse people who are used to excusing Aunt Sally.

What I would expect from _Ok?_ is to raise a compiler error on expressions such as `a + b * c`, and require that the programmer either changes the order, or adds parentheses.
