How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. design-patterns), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
lang-scala
tryandcatchis a fair argument, but couldn't this be easily achieved withTry? 2. StoringEithers in data structures could be done alongside thethrowsmechanism; isn't it simply an extra layer on top of handling failures? 3. You can definitely extendExceptions. Sure, you can't change thetry-catchstructure, but handling failures is so common that I definitely want the language to give me a boilerplate for that (which I'm not forced to use). That's like saying that for-comprehension is bad because it's a boilerplate for monadic operations.Eithers can be extended, where clearly they cannot (being asealed traitwith only two implementations, bothfinal). Can you elaborate on that? I'm assuming you didn't mean the literal meaning of extending.
