Is there any function in std library to partition a string into Pair. I wanted to created pair from a property string. What i am doing right now is, 
```   
val tuple = "key=value".split("=")
val pair =  when {
                  tuple.size &gt; 1 -&gt; tuple[0] to tuple[1]
                  else -&gt; tuple[0] to ""
               }
```

suresh: What I could come up with:
```
val tuple = "key=value".splitToSequence("=")
val pair = (tuple + generateSequence { "" }).take(2).toList()
```

Actually, that produces a list, not a pair. Hm.

How about this?
```val tuple = "key=value".split("=") + ""
val pair = tuple[0] to tuple[1]
```

~`tuple[1]` will throw if there is no `=` in the string~ missed `+""` sorry
