Detailed Description

_ – the destination that keeps nothing.

Written where a pipe's target goes and nowhere else: _ is not a name, so nothing may be bound to it and nothing may be read from it. A node of the grammar rather than a name the resolver happens not to find, for the same reason [It] is one – the position it is legal in is part of the language, and a wrong position should say what is wrong rather than "unknown".
