Hi Paul,

Yes, You're right. 

Perhaps 'Shortcut for creating map from an object' would be a better summary for this ticket.

Earlier I was thinking of having something like:
{code:title=Example|theme=FadeToGrey|linenumbers=true|language=groovy|firstline=0001|collapse=false}
def heroNoWeakness = hero.with{['name', 'strength', 'constitution']}
{code}

or maybe:
{code:title=Example|theme=FadeToGrey|linenumbers=true|language=groovy|firstline=0001|collapse=false}
def heroNoWeakness = hero.without{['weakness']}
{code}

> It would be nice if Groovy allows developers to create a map from selected properties of an Object.
> Below are the example:
> {code:title=Example|theme=FadeToGrey|linenumbers=true|language=groovy|firstline=0001|collapse=false}
> class Hero {
>     String name
>     Integer strength
>     Integer constitution
>     String weakness
> }
> Hero hero = new Hero(name: "Robin", strength: 70, constitution: 80, weakness: "Beautiful Women")
> def mapNoWeakness = hero.asMap(['name', 'strength', 'constitution'])
> println mapNoWeakness // [name: 'Robin', strength: 70, constitution: 80]
> def mapOnlyName = hero.asMap(['name'])
> println mapOnlyName // [name: 'Robin']
> {code}
