Local closures aren't lowered correctly

[feds01]

The following snippet:

foo := (x: i32) -> i32 => {
    double_and_shift := (y: i32) => 3 + y;
    double_and_shift(3) + double_and_shift(4)
}

This should not fail to compile, the issue is that the borrowed closure in the function is not assigned to the value.

Instead, the compiler panics.
