例如 x = 123p = Proc.new { x = 'I do not want change the value of the outer x, I want to create a local x'} 在Ruby中是否有与Perl中的“my”关键字相同的东西？ 根据 my 的Perl文档,我认为你在Ruby中寻找类似下面
x = 123
p = Proc.new {
x = 'I do not want change the value of the outer x, I want to create a local x'
}
在Ruby中是否有与Perl中的“my”关键字相同的东西？
根据 my的Perl文档,我认为你在Ruby中寻找类似下面的内容： –x = 123
p = Proc.new {|;x|
x = 'I do not want change the value of the outer x, I want to create a local x'
}
p.call
# => "I do not want change the value of the outer x, I want to create a local x"
x # => 123
