I get your point about it being a trick question but I think in this case it's pretty reasonable that you would see code like this in real life. Where the programming metaphor and your understanding of the real world clash. It's a very important skill to be able to spot the difference.

The compiler or interpreter does that for you. There's no point in these "gotcha's". They are cute brain teasers that belong on those useless "are you a programmer" quizzes you find on random meme websites, not an exam.

In the error shown a compiler would be just fine and run as usual but the person programming it would be expecting a different result so a compiler wouldn't do this for you since it's a logical error and not a syntax error.

If it's a statically typed language and x is of type Date, it's for sure throw a type error when trying to assign a string to it. If it had autoboxing / auto type conversion from String to Date, length could return a number or a string.

If this were Javascript on NodeJS, it would fail at print(x) because that doesn't exist in JS. If it were Python it would fail at x.length because that has to be len(x). And so on.

If this were all to pass, at the latest at runtime, when the programmer sees the output "6", they would know something's up.

As I said, cute, but worthless test.
