I'm also going with ~>. Visually the squiggle (tilde), to me, looks like a "tentative dereference".

Btw, I really can't wait. I'll be able to pull horrible hacky code such as:

    package MyApp::Universal;

    use warnings; use strict;
    use Try::Tiny;

    sub deref {
        #
        # Weak linear dereferencing. $foo->deref('bar','baz')
        # is almost like $foo->bar->baz except we'll
        # return undef rather than barfing if 'foo'
        # or 'bar' evaulate to undef.
        #
    
        if (@_ >= 2) {
           my $ref = shift;
           my $deref = shift;

           return unless defined $ref
           && defined $deref
           && try {$ref->can('isa')};

           return deref($ref->$deref => @_);
        }
        elsif (@_) {
            return shift;
        }
        else {
            return;
        }
    }

They I can go through my code and refactor....

    $obj->deref(qw(foo bar baz));
[download]

as....

    $obj~>foo~>bar~>baz;
[download]

Update Also look forward to be able to do...

    $href~>{foo}~>[$bar]~>{baz};
[download]

...when I don't want autovivification.
