States for the InvokeComposedStep intent.

Variants

EvaluatingFunc

Evaluate step function and leave it on the value stack.

Transitions to EvaluatingArgs.

EvaluatingArgs

Evaluate argument expressions, then pop them off the value stack. Then, before transitioning, pop the function off the value stack and store it.

Transitions to PreCall or PreTemporalCall.
