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 ${"STR"}
is always the symbol table variable, while ${STR}
may be the lexical variable. If it's not a
bareword, you're playing with the symbol table
in a particular dynamic fashion.
