If you are going to build a DSL, you might as well make it easy to read.
In this case I'd throw out the brackets, colons and dots.
It's 'just' a string transform inside the DSL compiler to get it back to what
the internals 'need', but it makes it a lot clearer.
Mind you, I've only built one DSL, and it's space was fairly constrained.
