different. This freezing can be shallow or deep (recursive). Example: s = |set(1, 3, 5)| d1 = |{s:1}| d2 = {d1:1} The "|" binary xor can become written "XOR", like the AND, OR, NOT. The &^~ so become free to be used for other purposes, operator overloading, etc (silly exampl

Freezing a mutable (was Re: lambda)

list and its copy but then mutate them differently, they no longer are equal and so wont get you at the same entry. The trick is that the result of the freezing operation is cached until such time as you explicitly unfreeze the object. Output: x: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] y: [0, 1, 2, 3, 4, 5, 6
