in thread Idiom: hashes as sets

  • A set containing some strings and some objects that behave as strings makes perfect sense to me. For example, a set that contains some strings from user input and other strings that live in a DBM::Deep DB.
  • No, I cannot presume all future requirements. But, I can presume that many future requirements will lead me to places that other peoples' future requirements led them. Therefore, with sets, I can guess that many future requirements will probably require one or more advanced set operations.
  • Given that most sets are implemented as hashes, this is a non-starter. And, the issue isn't one of whether or not the hash operations are going to work. The issue is whether or not my implementation of the pieces of set theory I need will be as correct as that in a well-used module. A hash is not a set.

My criteria for good software:
  1. Does it work?
  2. Can someone else come in, make a change, and be reasonably certain no bugs were introduced?

[LanX]: see soundfile https://en. wiktionary.org/ wiki/human# Pronunciation
[Your Mother]: Just Another Perl 'Acker.
[LanX]: I pronounce it 'juːmən'
[Your Mother]: Hey, let's not bring antisemitism into the conversation.
[LanX]: for centuries posh English speakers tried to approach French, that's where all the trouble starts
[Eily]: Just another Perl coeurs
[Eily]: (perl with hearts, 'Acker with a French accent is pronunced like coeurs)
[LanX]: IMHO 'ju' for 'u' happens in English where they can't pronounce the French u (or German )
[LanX]: and I'm sure I read that *hotel* used to be pronounced 'otel by the English upperclass
[Your Mother]: American English vowels are pretty lazy/mumbly in general.
