|x| |y| x + z

EXPECTED

UNDEFINED VARIABLE - lambda_invalid_references.md:1:13:1:14 UNUSED VARIABLE - lambda_invalid_references.md:1:6:1:7

PROBLEMS

UNDEFINED VARIABLE Nothing is named z in this scope. Is there an import or exposing missing up-top?

lambda_invalid_references.md:1:13:1:14:

|x| |y| x + z

UNUSED VARIABLE Variable y is not used anywhere in your code.

If you don't need this variable, prefix it with an underscore like _y to suppress this warning. The unused variable is declared here: lambda_invalid_references.md:1:6:1:7:

|x| |y| x + z
