| InvalidLen occurs when an argument to the len built-in function is not of |
| supported type. |
| |
| See https://golang.org/ref/spec#Length_and_capacity for information on |
| which underlying types are supported as arguments to cap and len. |
| |
| Example: |
| var s = 2 |
| var x = len(s) |
| ``` |
