> In a way you could say there is a sigil for each ref-type, when it gets deferenced (or when it is actually used as the base type, and not a reference in a scalar), @ => @$, % => %$, & => &$.
Alas, it's more complicated than this.
Just to give you one example, if you have a nested structure you have to write something like push @{ $ref->[1][2][3] }, "elem"
Very motivating for beginners! :(
In most other languages you can simply write something like push ref[1][2][3] , "elem" ...
