I like this... We could thing about the key a bit more but the concept is cool. How would I use this?

${postDateTime | timeAgo & signal:'my-signal'}

and hopefully like as custom updateTrigger
if.bind="myPara | signal:'token-expired'"
aka the bind will be checked when token-expired is signalled

Oooooh that's cool. :D

ps: i'm open to change to a better signal name 😄

I think I can live with this for now.
