First, if you like to memorize stuff, you can remember which gets

I read an interesting post recently dealing with this subject (the
sprinkling of parentheses), an interesting read.

That advice makes sense in a symbol-heavy language. Perl's operators
require programmers to know the interaction between symbols almost by heart.
But in languages that prefer words over symbols, operator precedence
beyond simple algebraic rules is rarely important, so knowing the entire
precedence order is not an important skill. Experts often completely
ignore it. Parentheses remain useful as a form of documentation in
complex expressions.
