Hi Jochen,
jshell, the equivalent of groovysh for java included in 9, does something l=
ike this,
it stores the content of all variables declaration as fields into a synthet=
ic class and all statements as method so statement have access to the conte=
nt of the field.

But because you have bindings in groovy, it may be simpler ? (i do not know=
 if bindings are typed ?)

cheers,
R=C3=A9mi
