I checked how other data types behave in Lua:

tarantool> "" > nil
---
- error: '[string "return "" > nil"]:1: attempt to compare nil with string'
...

tarantool> "" == nil
---
- false
...

tarantool> "" ~= nil
---
- true
...

tarantool> "" < nil
---
- error: '[string "return "" < nil"]:1: attempt to compare string with nil'
...

tarantool> 1 > nil
---
- error: '[string "return 1 > nil"]:1: attempt to compare nil with number'
...

tarantool> 1 == nil
---
- false
...


So, good point, I agree.
