I feel a little reluctant to approve this but I'll have to give my +1
just for the sake of consistency. Computed properties already use
colons despite being internally just functions just like subscripts
and the syntax is almost the same. I agree there may be an issue with
readability but so do with computed properties and I didn't see anyone
complaining about that syntax.

Despite accepting the change, I still don't think it is significant
enough. It is merely a cosmetic change that adds/enhances nothing to
the language.

I'm not sure but it grants a bit more of consistency in its syntax.

Other languages I worked with make no distinction on how you declare
the type of variables, function returns and properties. I'm not saying
"drop the arrows" thou.

Read the proposal and followed the thread discussing it.
