Planned This feature is planned but not yet implemented.
Requires a transform to handle pattern branches.

// Test: Pattern branch dispatch
//
// Pattern branches should dispatch based on matching the pattern against
// the event's return value. This test uses actual pattern branch syntax.
//
// The transform should:
// 1. Detect pattern branches (branch name starts with '[')
// 2. Parse the pattern to extract method + path template
// 3. Generate dispatch code that matches against the payload
// 4. Extract path params into the binding
~import std/io
const std = @import("std");
// Request type - the payload we're matching against
pub const Request = struct {
method: []const u8,
path: []const u8,
};
// Params extracted from path
pub const Params = struct {
id: ?[]const u8 = null,
};
// Event that returns a request
~pub tor incoming {} -> Request
~proc incoming|zig {
return .{ .method = "GET", .path = "/users/42" };
}
// This is what we WANT to work:
// Pattern branches dispatch based on matching method + path
