(unimportant questions about Lua design and implementation)
Hi!
It was impossible in Lua 5.2, but is possible since Lua 5.3:
There exist numbers x and y such that
assert(x > y and x - y == 0)
This potentially could break the logic of your script.
When migrating old projects to newer Lua versions,
make sure your application withstands new options of maliciously crafted input.
