... (streaming operator)

[emil14]

Before

getList -> listToStream -> forEach
getDict -> dictToStream -> forEach

After

getList... -> forEach
getMap -> forEach

---

Props: this way we don't have to memorize naming for these convertors

Cons: doesn't cover case with arr-ports

[emil14]

another way is

getList -> ... -> forEach

this might be better because of the same problems with struct selectors (also existing struct selectors could be sender/receiver kinds/expressions themselves)

[emil14]

XXX... allows more obvious usage in for statements

'''
for xxx... {

}
'''

OTOH 'xxx -> ... ->' allows multiple receivers flexibility

xxx -> [foo, ... -> bar]
