If it helps with porting and updating DWT, 'String' could be added for 
internal use.  Or maybe 'jstring', to give a unique name?

'string' is more problematic, since it would conflict if tango adds it 
too, leading to some user confusion until it can be fixed.  This can of 
course be avoided by using the trick[1] that Thomas Kuehne posted last 

But if it's called 'string', it'll in reality become a part of DWT's 
public api, and hard to remove later.  So I think it's good to stay away 
from that exact name unless Tango adds it.

static if(!is(string)) {
    static if(!is(typeof((new Object()).toString()) string)) {
       alias char[] string;
