// std/void — the explicit no-op.
//
// A void tor whose body does nothing is either a lie or a hole. Written
// `close -> {}` it is a silent hole — the render reads like finished work and
// nothing in the corpus or the toolchain can tell a placeholder from an
// implementation. Written with no body at all it is a legal *contract* (the
// compiler refuses it only when invoked), but absence is equally silent.
//
// `std/void:placeholder` is the third spelling: a named, first-class artifact
// that the whole toolchain can see. `koruc` can walk the AST, find a verb
// whose body points here, and tell you the vocabulary is unfinished; a gate
// can refuse a scope where a placeholder is still reachable at publish time.
// The no-op stops being a convention and becomes data.
//
// A verb delegates to it when it exists to hold a place in a vocabulary but
// has no effect yet: `close = std/void:placeholder()`. When the verb gets its
// real body, the delegation is deleted.
