[quotemstr]

Generally looks good, but ugh, I dislike allowing single quotes. Allowing single quotes has close to zero ergonomic value but increases the number of ways to write the same fundamental thing.

But that's a minor quibble. If everyone adopted this thing instead of legacy JSON, we'd be better-off.

Having two ways to quote is a useful feature, not just one way to do the same thing.

Javascript already has this, so allowing single quotes simplifies copypasting object literals, which is a common use case.
