If EXPR is an arbitrary expression, what is the difference between $Foo::{EXPR} and *{"Foo::".EXPR}?
If EXPR is an arbitrary expression, what is the difference between $Foo::{EXPR} and *{"Foo::".EXPR}? The second is disallowed under `use strict "refs"'.

What's the difference between /^Foo/s and /^Foo/?
