Let me try to summarize what I understood from your excellent explanation:

Putting a modifier in front of a reference dereference it to the right 
type ($ for scalar etc.). Alternatively, putting a '->' (which is a 
unary operator, not a binary one) also dereferences it, no matter what 
it is pointing to.(at least for array and hash), so long as there is 
some reference to its content on the operator's right (the same as it is 
implemented in C++, only more confusing).

The curly braces act as a scoping operator, making the $/@/% relation to 
parts of the expression unique.

All that is left is understanding why the round braces around the whole 
expression.

Many thanks (the explanation was very useful)
