The doubling up of the parentheses here has absolutely no effect.

Maybe you mean to pass a singleton tuple, in which case you
need to use the following syntax:

      foo(('this string available',))

The easy-to-miss trailing comma is what denotes the singleton
tuple -- unpleasant, but I know of no better alternatives.
