Re: Use of both numbered constants and strings

Quick question on this from an API user's perspective -

When I write an expression such as this -
	aPannerNode.panningModel = aPannerNode.EQUALPOWER;
the JS doesn't care what type the panningModel is,
as long as the types on either side of the assignment are compatible.

So would there be serious compatibility issues if implementors only
chose to use string enums and defined a property called EQUALPOWER
whose value is the string "equalpower" (instead of the integer 1)
for backward compatibility?

I'd expect most code uses such symbols instead of doing
	aPannerNode.panningModel = 1;
