${'a'} is a symbolic reference. The latter is forbidden under strict, and that's a good thing, as it can easily cause all kinds of hard-to-debug chaos

Perhaps a silly question but I don't know the answer so I shall ask it anyway...
Is there ever a case to use a symbolic reference in Perl? The documentation doesn't give any hint as to why one would be needed other than to describe them as powerful.
