> Given this code:
> {code:java}
> @Lazy
> Foo foo
> abstract class Foo {}
> {code}
> You'll get:
> {code}
> java.lang.InstantiationException
> 	at sun.reflect.InstantiationExceptionConstructorAccessorImpl.newInstance(InstantiationExceptionConstructorAccessorImpl.java:48)
> 	at java.lang.reflect.Constructor.newInstance(Constructor.java:526)
> 	at org.codehaus.groovy.reflection.CachedConstructor.invoke(CachedConstructor.java:80)
> 	at org.codehaus.groovy.runtime.callsite.ConstructorSite$ConstructorSiteNoUnwrapNoCoerce.callConstructor(ConstructorSite.java:105)
> 	at org.codehaus.groovy.runtime.callsite.CallSiteArray.defaultCallConstructor(CallSiteArray.java:60)
> 	at org.codehaus.groovy.runtime.callsite.AbstractCallSite.callConstructor(AbstractCallSite.java:235)
> 	at org.codehaus.groovy.runtime.callsite.AbstractCallSite.callConstructor(AbstractCallSite.java:239)
> {code}
> This isn't really helpful. If I mistype a method name, Groovy will help me out with suggestions,
why not here?
> MODIFICATION by blackdrag:
> @Lazy should recognize this and fail compilation to avoid the initialization of an abstract
class.
