-
-```ignore

-You have two possibilities to solve this situation:
-
-* Give an explicit definition of the expression
-* Infer the expression

-Examples:
-
-```
-let x = |_ : u32| {}; // ok!

-
-```ignore
-// could be an array of anything
-let x = []; // error: cannot determine a type for this local variable
-```
-
-To solve this situation, constrain the type of the variable.
