A scry is a read-only request to the namespace of a local vane or agent. In Hoon, scries are performed with the .^ rune. Unlike other kinds of inter-vane or inter-agent communications, scries cannot alter the state of the ship or produce other side-effects. Additionally, scries are an exception to the purity of Hoon functions, and can be performed in-line. The scry interface is also exposed through Eyre, the web-server vane, to web clients.
