+There is no longer any difference in the parsing of identifiers
+specified by using braces versus without braces.  For instance, perl
+used to allow C<${foo:bar}> (with a single colon) but not C<$foo:bar>.
+Now that both are handled by a single code path, they are both treated
+the same way: both are forbidden.  Note that this change is about the
+range of permissible literal identifiers, not other expressions.
