tchrist would probably agree that $addresses[🙈][🙉][🙊] looks pretty, but you probably can't get it to compile without a source filter or patch.
The biggest problem is that those aren’t even identifier characters: 
% uniprops 1F648 1F649 1F64A
U+1F648 ‹🙈› \N{SEE-NO-EVIL MONKEY}
    \pS \p{So}
    All Any Assigned InEmoticons Common Zyyy Emoticons So S Gr_Base
       Grapheme_Base Graph GrBase Other_Symbol Print Symbol X_POSIX_Graph
       X_POSIX_Print
U+1F649 ‹🙉› \N{HEAR-NO-EVIL MONKEY}
    \pS \p{So}
    All Any Assigned InEmoticons Common Zyyy Emoticons So S Gr_Base
       Grapheme_Base Graph GrBase Other_Symbol Print Symbol X_POSIX_Graph
       X_POSIX_Print
U+1F64A ‹🙊› \N{SPEAK-NO-EVIL MONKEY}
    \pS \p{So}
    All Any Assigned InEmoticons Common Zyyy Emoticons So S Gr_Base
       Grapheme_Base Graph GrBase Other_Symbol Print Symbol X_POSIX_Graph
       X_POSIX_Print
And Perl isn’t fond of random symbols appearing where it is expecting a TERM.
