in thread Context aware functions - best practices?

Perl 5.8.0 comes with Scalar::Util. One of the subroutines provided by this module is reftype(). reftype() is superior to UNIVERSAL::isa() in this context. For blessed or non-blessed array references, reftype() will always return 'ARRAY'.

Personally, I plan to use Scalar::Util::reftype() quite a bit in cases where I used to use UNIVERSAL::isa().

    Yup. Thats a good solution too. :-)

    Too bad it wasnt standard kit earlier on. In fact, too bad that reftype wasnt accepted as a pure perl keyword. Likewise for most of the modules contents.
