可以重写/实现的ruby操作符列表

这里是 a table of the Ruby operators .

可重载的方法有:

[ ] [ ]=    Element reference, element set
**  Exponentiation
! ~ + -     Not, complement, unary plus and minus (method names for the last two are +@ and -@)
* / %   Multiply, divide, and modulo
+ -     Plus and minus
>> <<   Right and left shift
&   Bitwise `and'
^ |     Bitwise exclusive `or' and regular `or'
<= < > >=   Comparison operators
<=> == === != =~ !~     Equality and pattern match operators (!= and !~ may not be defined as methods)

这个表来自2001年的Pickaxe手册,但它与Ruby1.9 Pickaxe手册中的表是相同的——没有理由相信这组中缀运算符会改变。
