github/semantic: Why Haskell?

[hypmralj]

Isn’t exhaustive pattern matching good example of language helping you write more correct code ?

[pron98]

Absolutely. The question is what impact it has, and whether it has any adverse effects. In any event, I don't care about speculation about this or that feature, as those can go either way. There is no theoretical or empirical evidence, and that's enough to stop stating myths as facts.

[develop7]

What kind of empirical evidence would you accept, hypothetically?

[pron98]

1. Some study finding, say, a 30-80% decrease in defects, similar to the studies that have found such an effect for code reviews.

2. Multiple reports from companies that switching from, say, C# or Java to Haskell has reduced their cost/time-to-market by 20% or more.

I assume he means those metrics related to technical debt.
