def 和 @Property

舊版本中（Groovy JSR 06 的之前版本）@Property定義一個帶有setter和getter的私有屬性，而def和java中public一樣，定義一個公共的屬性。

后來@Property已經從Groovy JSR 06中移除，在Grails 0.2和之后的版本中也不會再需要它 。

現在def用來定義一個帶有setter和getter的私有屬性，來代替了@Property。

Proposed

code	field	getter	setter	note
def x
final x				the field doesn't need to be final IMHO (dk) My view is that the field should be final(tug)
public x
protected x
private x
public final x				a public final field like in Java
@Property x				if it's still supported (MrG) My proposal is to remove it (tug)
other permutations?				what happens with static? (MrG) Static behave exactly the same(tug)
