Re: how to avoid mis-spelling hash keys?

[Beatnik]

You can just abuse String::Approx for approximate string matchings :)

You don't have to abuse anyone ;-)

Using Tie::Hash::Approx suffices.

I think doing approximate string matches for hash keys in objects would be the programmer's equivalent to playing Russian Roulette. Bad idea.

[Beatnik]

Well, if there is an exact match, it's no roulette. There are quite simple techniques to verify a hash key actually exists. In fact, like janx noted above, there's Tie::Hash::Approx by our very own OeufMayo which does pretty much just that :)

davorg is (sometimes) an evil man. Whenever somebody brings up this subject I always am reminded of his talk introducing Symbol::Approx::Sub and friends - and smile evilly.

Evil? Me? Surely you're thinking of someone else :)

Is this the talk you mean?

/me attended both talks you did in Amsterdam in 2.00.1 and didn't notice anything evail about it :)

Precisely! I enjoyed it immensely.
Especially after I found out about Tie::Hash::Cannabinol - a CPAN module I would enjoy finding a serious use for. I've been close to using it in production, but lacked the courage. I'm still working on it though :)
