If syntax sugar

[emil14]

See #724

$bool -> if {
    then -> receiver_1
    else -> receiver_1
}

Before

flow Main(start) (stop) {
	Println, Gt<int>, If
	---
	:start -> [
		(10 -> gt:compared),
		(50 -> gt:actual)
	]
	gt -> if
	if:then -> ('Actual is greater' -> println -> :stop)
	if:else -> ('Actual is lower' -> println -> :stop)
}

After

flow Main(start) (stop) {
	Println, Gt<int>
	---
	:start -> [
		(10 -> gt:compared),
		(50 -> gt:actual)
	]
	gt -> if {
	    then -> ('Actual is greater' -> println -> :stop)
	    else -> ('Actual is lower' -> println -> :stop)
	}
}

Without incoming ->

def Main(start) (stop) {
	Println, Gt<int>
	---
	if (10 == 50) {
	    then -> ('Actual is greater' -> println -> :stop)
	    else -> ('Actual is lower' -> println -> :stop)
	}
}

About if-else branching

I was thinking about if {...} else {...} but there's a problem - we need to route signal from then/else outports to trigger downstream nodes, i.e. we need then -> and else -> stuff

PROBLEM

How should it work with deferred connections? We just omitted :start here!

[emil14]

Maybe match switch is enough?

If match will allow not only to select value but also trigger branch (routing), then if is barely needed

v -> switch {
  true -> ...
  false -> ...
}

Vs if-else

v -> if {
  then -> ...
  else -> ...
}
