Not so fast… It seems a similar issue affects String.replace(re, …). See
for yourself with the following example:

  import QtQuick 2.0
  Item {
    Component.onCompleted: "bla".replace(/\w/g, function(a) { return
a.toUpperCase() })
  }

I’ll look into working around this issue tomorrow, but I think we should
also consider looking into Qt’s code ourselves and see if we can come up
with a patch, in case upstream is not responsive enough.

Cheers,

 Olivier
