Patch to fix this problem. Not sure if it is the route you want to take as it doesn't know anything about string interpolation of the form "hello $

{world}

" but it does let the println("Hello World") pass.

This passes the unit test but is not a good solution. Will provide a more robust patch later this morning (hope you don't mind patches from the peanut gallery). Breakfast calls at the moment,

Fixed now.

println("hello") and print(whatnot) can be called now from anywhere.

The old style

"hello".println() have gone now.
