Re^3: Report on Blessing to 'tag' an object

That won't always work: Can't locate Scalar/Util.pm in @INC Which do you think is more likely? 1) That I blessed a non-array reference into the package named 'ARRAY' and I'll be upset that UNIVERSAL::isa() gets confused or 2) That I don't have Scalar::Util ?

I think Scalar::Util has become "core" and so in a few years, the probabilities will shift. For now, I much prefer UNIVERSAL::isa() because I like my code to work on relatively old versions of Perl and I don't mind that it is possible to break my code by doing extremely stupid things. q-:

Fair point :-) Scalar::Util has been core since 5.007003 for those interested. Personally, I prefer catch the weird cases - even if I have to install a few modules to do so.	[reply]

This particular module should be useful without other (non-core) dependancies, and should run on Perl 5.6. There is another place Scalar::Util would come in handy (to distinguish a floating-point literal from a string literal), but I'm trying to do without. I thought about using isa rather than ref, but figured the latter is faster and I know exactly what the possibilities are. That is, I won't see a derived class coming back in.	[reply]

If you are that concerned about module dependencies there is always the option of a copy 'n' paste of the pure perl version :-) Read more... (1132 Bytes)	[reply] [d/l]
