Let us see?

Which assignment Matz?

irb(main):001:0> def x;1 end
=> nil
irb(main):002:0> if false then
irb(main):003:1* def x; 2 end
irb(main):004:1> end
=> nil
irb(main):005:0> x
=> 1
irb(main):006:0> def y; 1 end
=> nil
irb(main):007:0> if false
irb(main):008:1> undef y
irb(main):009:1> end
=> nil
irb(main):010:0> y
=> 1

Surely the statements inside if are not executed.

Cheers
