in reply to Use case for symbolic references (was: Re^2: Referencing the locals)
in thread Referencing the locals

Is there ever a case to use a symbolic reference in Perl?

Two places that come to mind where I regularly write no strict 'refs'; is dynamic method/function generation (example 1, example 2) and implementations of import (example 1, example 2, at the bottom of each node). Other than those legitimate uses, there's interaction with legacy code (example 1, example 2). Note how in each of those examples the scope of the no strict is limited to be as small as possible.

Update: Added more links to examples.
