= Precedence

From highest to lowest, this is the precedence table for ruby.  High precedence
operations happen before low precedence operations.

!, ~, unary +

unary -

*, /, %

+, -

<<, >>

|, ^

>, >=, <, <=

<=>, ==, ===, !=, =~, !~

.., ...

?, :

modifier-rescue

=, +=, -=, etc.

defined?

not

or, and

modifier-if, modifier-unless, modifier-while, modifier-until

{ } blocks

Unary <code>+</code> and unary <code>-</code> are for <code>+1</code>,
<code>-1</code> or <code>-(a + b)</code>.

Modifier-if, modifier-unless, etc. are for the modifier versions of those
keywords.  For example, this is a modifier-unless statement:

a += 1 unless a.zero?

Note that <code>(a if b rescue c)</code> is parsed as <code>((a if b) rescue
c)</code> due to reasons not related to precedence. See {modifier
statements}[control_expressions_rdoc.html#label-Modifier+Statements].

<code>{ ... }</code> blocks have priority below all listed operations, but
<code>do ... end</code> blocks have lower priority.

All other words in the precedence table above are keywords.
