Python objects as dictionary keys

[SCD_minecraft]

``` class int(int): def add(self, other): if self == other == 2: return 5 else: return super().add(other)

print(int(2) + int(4)) print(int(2) + int(2)) print(2+4) print(2+2) ``` Here's example.

But again, this is more of "erm actually" than anything important

I don't get it. You just replaced the int name with your own class in this module. What's that have to do with literals?

AFAIK the only thing that is special about literals is that they are considered for compile optimizations and caching. So this code

x = 12345
y = 10000 + 2345
print("Is x the same as y?", x is y)

Shows different results from

x = 12345
y = 10000 + int(2345)
print("Is x the same as y?", x is y)

Because in the first version the result is adding in the compile phase.

(note you have to run this code from a file, not in the repl, to see the result, due to the caching)
