Reduce noise when using ports by replacing `:` with `.`

[emil14]

We use : to refer ports:

node:outport -> node:inport

The reason for that is that we need . to access struct fields:

node:outport.foo.bar -> ...

However, syntax for this might change with new #syntax for struct fields selection

node:outport -> .foo.bar -> node:inport

Proposal

How about this

node.outport -> .foo.bar -> node.inport

Downsides

I don't really like how self ports looks tho. But maybe that's just a habit?

.start -> .stop

Also we mix port refs with struct fields refs. However, conventional languages tend to use . for a lot of stuff too. E.g. Go uses it for both referring to package entities and struct fields

I don't think I like it... Lol, : aren't bad at all actually. It's good to distinguish between ports and struct fields.

Yeah but we going to use it for 3 things this way, which is even worse
