Are questions about language design on-topic?
I was chatting with somebody who's involved with a proposal on SE for a site about language design and who is interested in other options too. Some sample questions:
What are the tradeoffs between explicit line-end syntax (like semicolons) versus newlines?
How could a parser implement custom infix operators?
How can I turn this left-recursive grammar into a rule that isn't left-recursive?
What are the advantages of compiling versus interpreting?
Are questions like these welcome on Software Development, assuming they're scoped to not be too broad?
I'm not trying to change scope (nor to interfere with an SE community); I just want to know if I should be encouraging or discouraging people who are considering asking those kinds of questions here instead of waiting.
