The Arrow Operator

Just as in C and C++, ``->'' is an infix dereference operator. If the right side is either a [...] or {...} subscript, then the left side must be either a hard or symbolic reference to an array or hash (or a location capable of holding a hard reference, if it's an lvalue (assignable)). See the perlref manpage.

Otherwise, the right side is a method name or a simple scalar variable containing the method name, and the left side must either be an object (a blessed reference) or a class name (that is, a package name). See the perlobj manpage.
