I know you were being a bit tongue-in-cheek, however I
would like to point out that the conceptual leap to
understanding that first-class continuations is to
understand that they offer the programmer a direct
instrument by which to create a stack-safe dynamic
goto label which can cross function-definition boundaries.
They're really nothing more than an instrument by which
the programmer can force their own context-switch.
Stacklessness isn't strictly required for this, it's
just considerably more efficient.
