Slow response, loading spinner while editing
Hi,
while editing in Haskell mode (Tidal Cycles files) Emacs quite frequently pauses, shows a spinner and I have to Ctrl-G to be able to go on. It happens mostly while deleting single characters. I can track it down to haskell-lexeme-looking-at-token

I am using a Thinkpad Yoga 1. Gen, 16 MB RAM, Intel Core i7-6600U CPU @ 2.60GHz × 2 with Linux Mint 20.3 Cinnamon and Emacs 27.1.; tidal-mode is tidal-20210211.1531 and haskell-mode is haskell-mode-20210908.1543 from elpa - if that is some crucial information.
Please let me know if more information is necessary to maybe look into that.
I tried the solution from #1648 but this did not help.
I'd be grateful for any hints to make the mode work.
this happens in combination with symbol-overlay, see also https://github.com/wolray/symbol-overlay/issues/75
