Make setting() function handle string concatenation more nicely?

[jlahijani]

Right now, we can assign a setting variable (specifically a string) like so: setting('foo', 'bar');

Later in my code I may want to update foo to be bar baz. Right now I have to do this: setting('foo', setting('foo').' baz');

That's less than ideal. Would there be some way to make it nicer?

What is your exact use case? Maybe there are other options, like using WireData instead?
