[flexcoders] Get strong propertyName from object so it would break at compile time if changed

[tntomek]

Is there a way to get a strong property name from an object?

scenario ... Person class having "weight" property

var column:DataGridColumn
column.dataField = "weight"; 

can i do something like:

column.dataField = Person.weight.getPropertyName();

... so that if this "weight" property is renamed one day I would get compile 
time warning?
