Description

support named parameter arguments such as

foo(a:1234, b:542)

Uses NamedArgumentListExpression which is-a MapExpression.

Right now we implement the above to match a method

foo(Map map)
foo(Object object)

though we should also allow it to invoke any Java method (or at least any groovy method). Though we need metadata of the names of the parameters to be able to do this.

Punting the rest of this bug to the backend. Still may have to change front-end to use a Tuple of MapEntryExpressions and Expressions, instead of a MapExpression/NamedArgumentListExpression.

We support this for

  • calling a method which takes a Map of parameters
  • creating a bean and setting properties

We don't yet support arbitrary invocation of any method using this mechanism

Named arguments are supported in method calls, constructor calls.
However, we can really use positional parameters for non map-based methods since there's nothing in the JVM/JDK to let us do that.
