@fullName Syntax error in param value using @member lookup
@description

Occurs when there is a syntax error when attempting to extract a param
value from the data object.

Here's an example of valid syntax for `params` or `paramsDefault`:

````javascript
{
  bar: '@foo.bar'
}
````

The part following the `@`, `foo.bar` in this case, should be a simple
dotted member lookup using only ASCII identifiers.  This error occurs
when there is an error in that expression.  The following are all syntax
errors

 | Value   | Error          |
 |---------|----------------|
 | `@`     | Empty expression following `@`. |
 | `@1.a`  | `1` is an invalid javascript identifier. |
 | `@.a`   | Leading `.` is invalid. |
 | `@a[1]` | Only dotted lookups are supported (no index operator) |
