I kind of like delimited continuations. It's easier to implement
coroutines with them, also they're more predictable. I think they can be
made into full-powered continuations with „THROW”/„RETURN-FROM”.

Also, CPS-transformation is kind of inefficient, Python (the language,
not the compiler) and C# went the correct route and implemented
coroutines as a special form only available in „define-generator”
functions, so not everything in the call stack has to be
CPS-transformed, only the tail of the „yield” expression.
