Thanks!  With that and https://wiki.haskell.org/Emacs/Indentation, I've
this in my Emacs init file now:

--8<---------------cut here---------------start------------->8---
(require 'align)

(add-to-list 'align-rules-list
             `(agda-colons
               (regexp . "\\(\\s-+\\)\\(:\\|∶\\)\\s-+")
               (modes . '(agda2-mode))))

(add-to-list 'align-rules-list
             `(agda-equals
               (regexp . "\\(\\s-+\\)=\\s-+")
               (modes . '(agda2-mode))))

(add-to-list 'align-rules-list
             `(agda-arrows
               (regexp . "\\(\\s-+\\)\\(->\\|→\\)\\s-+")
               (modes . '(agda2-mode))))

(global-set-key (kbd "M-[") 'align)
--8<---------------cut here---------------end--------------->8---

I don't know if I'll need to align equals and arrows, but no harm having
them also in the rules.

Cheers,
Raghu.
