Ternary operator syntax

[emil14]

See #721 this is an extension

(bool_sender ? res_sender1 : res_sender2) -> dst

Before

flow Main(start) (stop) {
    Eq, Ternary, Println
    ---
    :start -> [(2 -> eq:actual), (2 -> eq:compared)]
    eq -> ternary:if
    'They match' -> ternary:then
    'They do not match' -> ternary:else
    ternary -> println -> :stop
}

After

flow Main(start) (stop) {
    Eq, Println
    ---
    :start -> [(2 -> eq:actual), (2 -> eq:compared)]
    (eq ? 'They match' : 'They do not match') -> println -> :stop
}

With #717

flow Main(start) (stop) {
    Eq, Println
    ---
    :start -> [2 -> eq:actual, 2 -> eq:compared]
    eq -> (eq ? 'They match' : 'They do not match') -> println -> :stop
}

Plus #721

In case these chains will support trigger semantics

flow Main(start) (stop) {
    Println
    ---
    :start -> ((2 == 2) ? 'They match' : 'They do not match') -> println -> :stop
}

[emil14]

Plus #721

Instead of adding trigger semantics to () we can use deferred connections here (if they are existing)

flow Main(start) (stop) {
    Println
    ---
    :start -> |((2 == 2) ? 'They match' : 'They do not match') -> println -> :stop|
}

Noisy AF but something to think about
