Uncaught effects

What happens to uncaught effects?

UncaughtEffectError: Effect was never caught by a handler: 'myEffect'
   ...stack trace...

Crazy idea: Prepend the @ symbol to any function call to assume purity. Maybe perform some memoization? Any uncaught effects would crash at the callsite.

let foo = fn (a, b) {
  effect a + b * Math.random()
}

let res = @foo(a, b)

Effects are not impure
