Yes, but that’s a very small chance. Especially for a well established language feature.
And I’d argue there’s at least as much chance of being given misinformation, or incomplete information, asking on a group like tutor!
 
But it’s always much quicker to ask the interpreter in the first instance. Then if doubt remains you can present evidence why you think things are other than they should be.
