@list = @$arrayref;

If EXPR is an arbitrary expression, what is the difference between $Foo::{EXPR} and *{"Foo::".EXPR}? The second is disallowed under `use strict "refs"'. Dereferencing a string with *{"STR"} is disallowed under the refs stricture, although *{STR} would not be. This is similar in spirit to the way ${"... 2013-09-16, 2669👍, 0💬

The deprecated $* flag does double duty, filling the roles of both /s and /m. By using /s, you suppress any settings of that spooky variable, and force your carets and d... 2013-09-12, 2434👍, 0💬
