I want to have reactive variables like in this example:
```
USING_REACTIVE_DOMAIN(D)
// The two words
VarSignalT firstWord = MakeVar(string( "Change" ));
VarSignalT secondWord = MakeVar(string( "me!" ));
// ...
SignalT bothWords = firstWord + string( " " ) +
secondWord;
```
from this page:
http://schlangster.github.io/cpp.react/tutorials/BasicSignals.html
Is this possible to make it in D with
https://github.com/lempiji/rx ? Is there other libraries exists
for this topic?
I think that it can use combineLatest which was recently added.
If using 'alias this' or 'operator overloading', might look like
more original example.

import rx;
auto firstWord = new BehaviorSubject!string("Change");
auto secondWord = new BehaviorSubject!string("me!");
auto bothWords = new BehaviorSubject!string("");
combineLatest!((a, b) => a ~ " " ~ b)(firstWord,
secondWord).doSubscribe(bothWords);
writeln(bothWords.value); // Change me!
firstWord.value = "TEST";
writeln(bothWords.value); // TEST me!
