Module threads 

Multi-threaded elisp support.

The go function spawns a new thread to evaluate an expression and returns a channel receiver that will eventually contain the result.

Result Format

• On success: The receiver contains the evaluation result
• On error: The receiver contains ('thread-errored . "error message")

Usage from Elisp

;; Successful evaluation
(let ((receiver (go (+ 1 2))))
  (channel-recv receiver))  ; Returns 3

;; Error handling with pcase
(let ((receiver (go (undefined-function))))
  (pcase (channel-recv receiver)
    (`(thread-errored . ,msg)
     (message "Thread error: %s" msg))
    (result
     (message "Got result: %s" result))))

;; Discard result (fire and forget)
(go (message "Background task"))
