final class SliceStep
Restricted visibility: declared "@visibility root". Code outside that scope must not name this declaration.

One thing that has to happen, on the way to the call, for its argument to have the value it has.

A step is the node that does it: an assignment, a global or static declaration, an unset, the start of one pass through a foreach, or a closure parameter taking whatever a caller passes. A step can instead hold alternatives — whole runs of steps, any one of which may have happened — when the paths had to be gathered up to keep their number bounded. Entering a closure is a step as well: the names it lists are the ones the closure defines for itself, as parameters or not at all, rather than taking them from the body it is written in.
