Re: context-sensitivity for selfwritten functions

[rob_au]

In order to distinguish between scalar and list return contexts, take a look at the wantarray function - See perldoc -f wantarray).

This functionality has been expanded further in the Want module which provides a greater generalisation of return contexts including top level contexts such as void, scalar and list, lvalue subroutine context and referential contexts (such as scalar, hash, array, object and alike).
