---------------------------------------------------------------
One additional difference exists between dynamic and static modes when it comes
to super class field access:
{code:groovy}
abstract class A {
public x = 'field'
protected y = 'field'
@PackageScope z = 'field'
}
class M extends A implements Map<String,String> {
// ...
void testRead5() {
println x // field
println y // entry (dynamic) or field (static)
println z // entry (dynamic) or field (static)
println this.x // field
println this.y // entry (dynamic) or field (static)
println this.z // entry (dynamic) or field (static)
}
void testWrite() {
a = null // field
b = null // field
x = null // field
y = null // entry (dynamic) or field (static)
z = null // entry (dynamic) or field (static)
println(this); clear()
this.a = null // field
this.b = null // field
this.x = null // field
this.y = null // entry (dynamic) or field (static)
this.z = null // entry (dynamic) or field (static)
println this
}
}
{code}
GROOVY-8978 is a variant of this.

> property semantics of map-based types (pt.2)

> Key: GROOVY-11403
> URL: https://issues.apache.org/jira/browse/GROOVY-11403
> Project: Groovy
> Issue Type: Improvement
> Reporter: Eric Milles
> Assignee: Eric Milles
> Priority: Major
> Labels: breaking
> Fix For: 5.0.0-alpha-9
>
>
> The property semantics for map-based types was recently updated (see
> GROOVY-11367). {{testRead3()}} and {{testRead4()}} demonstrate the desired
> outcome: public members (except {{isEmpty()}} and {{getClass()}}) then map
> get/put.
> {{testRead1()}} and {{testRead2()}} demonstrate the differing semantics for
> {{this}} references: accessible fields and public methods then map get/put.
> Why the difference between fields and methods? Also there are differences
> between dynamic and static compilation modes (as noted).
