Thank you.
good to know of "use strict"; a feature that will certainly help. It'd be nice to be able to turn off on a per file basis. For example, in in the beginning of legacy files one can put "use strict not"; or something similar.
Can you apply "use strict" to the entire Java engine? (like you would server side with C# with web.config)
It seems to be a great way to do final runtime checks on your farm of test machines - that, as you say, might concat' in a different order.
