is def method good enough for you?

irb(main):001:0> def m
irb(main):002:1>    var = 2
irb(main):003:1>    puts "inner var = #{var}"
irb(main):004:1> end
=> nil
irb(main):005:0> var = 1
=> 1
irb(main):006:0> m
inner var = 2
=> nil
irb(main):007:0> puts "outer var = #{var}"
outer var = 1
=> nil

you can nest methods too

irb(main):008:0> def m2
irb(main):009:1>    var = 1
irb(main):010:1>    def m3
irb(main):011:2>        var = 2
irb(main):012:2>        puts "inner var = #{var}"
irb(main):013:2>    end
irb(main):014:1>    puts "outer var = #{var}"
irb(main):015:1> end
=> nil
irb(main):016:0> m2
outer var = 1
=> nil
irb(main):017:0> m2.m3
outer var = 1
inner var = 2
=> nil
irb(main):018:0> m3
inner var = 2
=> nil
