Examples of NamedExpression

com.github.sommeri.less4j.core.ast.NamedExpression
com.google.dart.engine.ast.NamedExpression
Instances of the class {@code NamedExpression} represent an expression that has a name associatedwith it. They are used in method invocations when there are named parameters.
```
 namedExpression ::= {@link Label name} {@link Expression expression}
