Oh monks most tawny and tangy, whose wisdom and knowledge of all things Perl is unalienable and indefeasible, help me out, for I'm very much missing the obvious.

As you will well know, Perl allows Unicode characters in variable names, so long as use utf8; is in effect. So the following snippet works as expected (apologies for the unresolved HTML entities, Perlmonks itself does not handle Unicode properly): 

    my $人 = "World";
    say "Hello, $人";

However, the following does not: 

    my $&#1F310; = "World";
    say "Hello, $&#1F310;";

[download]

Perl 5.20.0 complains about this, saying: 

    Unrecognized character \x{1f310}; marked by <-- HERE after my $<--
+ HERE near column 5 at 1123740.pl line 9.

[download]

This is even though the character is in Unicode 6.3.0, which Perl 5.20.0 supports.

So why isn't it working? Help me out, fellow monks.
