Just reading the #Lean tutorial. Using special Unicode angle brackets that look visually similar to regular angle brackets is a surely just asking for confusion.
In these contexts, the arguments can be enclosed in angle brackets ⟨ and ⟩. A Point can be written ⟨1, 2⟩. Be careful! Even though they look like the less-than sign < and greater-than sign >, these brackets are different. They can be input using \< and \>, respectively.
