The following module was proposed for inclusion in the Module List:
modid: Contextual::Return::Wrapper
DSLIP: bdppp
description: Modifies functionality based on wantarray
userid: TQISJIM (Jim Schueler)
chapterid: 2 (Language_Extensions)
communities:

, module-auth...@perl.org, perlmonks.com
similar:
Attributes::Context
rationale:
My module wraps an arbitrary user-defined function so that it
responds differently based on the context established by querying
wantarrray for context eg (array/scalar/void). In this case,
wantarray is automatically implemented by the wrapper.
Users who implement Conway's Contextual::Return need to define the
functionality for each context definition. My module uses
pre-defined functionality established by the calling function
attributes. The value of this module is to standardize the
implementation of common functionality.
So this module is similar to Conway's in that the functionality is
determined by the calling context. And different in that the
functionality is pre-defined.
This module uses a wrapper to achieve the same functionality as
Conway's Contextual::Return. But since it does not literally wrap
his module, the name Contextual::Return::Wrapper may be
inappropriate. In that case, I will re-apply for Wantarray::Wrapper,
which requires a new root namespace.
The primary difference between my module and Ovid's
Attributes::Context are the attribute signatures. I have also added
a few additional pre-definitions.
