I'd call this a non-argument performance and otherwise given that
even the inventor of NULL regretted this his invention, see

https://en.wikipedia.org/wiki/Tony_Hoarehttps://en.wikipedia.org/wiki/Tony_Hoare

in this quote

"I call it my billion-dollar mistake. It was the invention of the null 
reference in 1965. At that time, I was designing the first comprehensive 
type system for references in an object oriented language (ALGOL W). My 
goal was to ensure that all use of references should be absolutely safe, 
with checking performed automatically by the compiler. But I couldn't 
resist the temptation to put in a null reference, simply because it was 
so easy to implement. This has led to innumerable errors, 
vulnerabilities, and system crashes, which have probably caused a 
billion dollars of pain and damage in the last forty years."
