pub const READ_ONLY_PLACE: &str = "cove::type::read_only_place";Expand description
A place let made read-only is written, passed as var, or given to a
var self receiver.
One code for the one rule — let creates a read-only place; var
creates a mutable place — however it is broken. The three messages differ
because what the program was doing differs; the fact reported is the
same, and a reader who wants to suppress or search for it wants all three.
