I understand that, it makes sense. But why does it not throw an error? The parameter is missing after all.
Actually the explanation is wrong.
is actually
notis a keyword not a function.Boolean of empty tuple is
Falseand thennotnegates it.I explained it better here:

That makes a lot more sense, thanks I did see in the syntax highlighting that it was a keyword but forgot that none of them took parameters.
No it's not, "" (a null/empty string) is the parameter. Not every function needs a parameter to be valid, and negation is one of them. Negating nothing is something, so "not()" = "not(null)" = "not(false)" = "true"
