> Collections are type-unsafe, so it is possible to write constraints on non-existing fields. The compiler will not report any error, but an exception will be thrown at runtime. 
> The configuration was needed to support map and list accessors:
> {code}
> Map( this[ "key" ].someFieldOfTheValue > 0 )
> {code}
> but an explicit cast would be preferable
> {code}
> Map( this[ "key" ]#ClassOfTheValue.someFieldOfTheValue > 0 )
> {code}
> This bug can't be fixed in 6.x due to backward compatibility. It will be fixed in future major versions.
