perl has no function arg list

Im learning a little perl and everything about perl is done in the worst and most convoluted way. Prime example being that function definitions dont have an argument list but rather an implicit list that is extracted from within the function by @_.
Why is there no explicitly declared parameter list. I got banned from #perl on freenode for asking this.

Like most dynamic languages you end up using refs to create complex structures.
no, perl is the only scripting language I know of that forces you to have to use indirection to access variables
