Hi Robert,
I found the motivation doesn't help to understand how jshell works.
At the end of the section, you're talking about removing the ceremony 
"class Foo { public static void main(String[] args) { ..." but this is 
not what jshell does, jshell only remove "class Foo {".

See my previous message on this list, variables in jshell are static non 
final fields and not local variables.

I don't think it's a good idea for a newbie to use a REPL that consider 
all variables as global,
said differently, I don't want to explain in the following example why 
the line with 'a' compiles but not the line with 'b'.

int a = a + 1
if (a == 1) {
   int b = b + 1;
}

cheers,
Rémi
