// Slots should be unique within children of particular node type.
// Non-negative numbers are used for slots in indexed container elements, for example, value arguments in a call.
// NB a node can potentially contain several "containers"; it's up to a node how to organize numbering in such case.
// Negative numbers are used for "named" slots, for example, dispatch and extension receivers in a call.
