Please support ES6 back-tick for strings

[intervalia]

ES6 has some wonderful functionality based on strings wrapped in the back-tick (`) instead of the standard double-quote (") and single-quote (') characters.

Please, PLEASE add full support for the ES6 back-tick functionality!

This is probably not that hard to implement as a syntax sugar. But the benefit of string interpolation is somewhat watered down by the existing support for Python string formatting:

local total = 37; 
The total is %g (%02g with tax)" % [total, total*1.05]

and the named version:

local o = {total: 37, withTax: 1.05*self.total};
"The total is %(total)g (%(withTax)02g with tax)" % o

which both yield:

"The total is 37 (38.85 with tax)"

With your proposal, you would also be able to do the somewhat similar-looking:

local total = 37;
`The total is ${total} (${"%02g" % (total*1.05)} with tax)`

Which would be desugared to

local total = 37;
("The total is " + total + " (" + "%02g" % (total*1.05) + " with tax)")

With that in mind, how badly do you still want it? :)

The main reason I would like to see the back-tick is because I sometimes I move code from a JS file into a JSON file and I hate that I need to undo the ES6 coolness.

It would just be nice to have but not needed.
