Imported Files

// Library module: fs
// Single disposal event

const std = @import("std");

const File = struct { handle: i32 };

// Open a file - returns opened! state (requires cleanup)
~pub event open { path: []const u8 }

// Close - the ONLY consumer of [!opened]
~pub event close { file: *File<!opened> }

~proc close|zig {
