Without the explicit recur it's far too easy to misidentify a tail call and use recursion where it's not safe.

Recur has zero inconvenience. It's four letters, it verifies that you are in a tail position, and it's portable if you take code to a new function or rename a function. What's not to love?

In what sense?

It's not really surprising. Hetero sexual desire has been framed negatively for well over a decade, as at best exploitative and at worst misogynistic and perverted. Men told that if you want sex you're part of society's biggest problem, and women told that if you give in to a man's sordid desires you are being taken advantage of and subjugated. All we ever talk about is the dreaded 'power imbalance'.

We've removed sex from normal life as far as possible. Films can be full of violence but any hint of titillation is verboten now. Any reference to sex in normal walks of life is seen as harassment, chauvinistic or pandering to the male gaze. Our culture is influenced by global social and religious conservatism in the quest to sell media to as many markets as possible. Our own new conservatism (the so-called left wing) is just as bad.

On top of that we have the culmination of a few decades of obsessive education about STDs and sex as a dangerous act that can ruin lives. A far cry from 'The Joy of Sex' as a cultural phenomenon.

We're letting prudes and those with deep psychological issues around sex call the shots. Millennials and Gen Z may be a lost cause, but let's hope that Gen A can rewrite the rules.

Age limits on buying cigarettes are easily thwarted by finding a corner shop that needs the sale and will sell to kids. Height restrictions on fairground rides are easily thwarted by putting bits of wood in your shoes. None of this matters.

The point is that this kind of control will drastically reduce under 18s consuming content that they shouldn't. We don't need the all of society's controls to be flawless.
