    There are various ways to try and get the source. Most of them strip off line feeds so if there is line comment (// ... ) the rest of the source turns into a comment *if* the source ever gets reparsed. NOTE this is exactly what happens with module. This tries to get the original source with line feeds and all. It may be more fragile than the ANTLR documentation lets on, so be advised. The ctx.getText() method, however, is definitely broken...

    Takes the place of having variables with .'s baked in to them and promotes the 'childOf' operator to a proper first class citizen of QDL. There are some edge cases though.
    First case of parsing is that in our grammar, x. - y. (and for that matter x. ~ y. with unary join) gets parsed as dotOp / | \ x . unaryMinus \ y. I.e. it thinks it is x.(-y.) The reason is that we allow for a. as an expression and ~b. as a monad, so it cannot tell a. (~b.) from (a.) ~ b. and the former certainly could also occur, but the latter is much more intuitive. We do not have this problem with x. * y. since there is no monadic *y. We don't want x.^y. to behave differently from x.-y. for instance. A lot of reading about possible solutions convinced me that fixing it after the fact was the way to go. Another options is a very careful restructuring of the grammar, but that is apt to be quite painstaking and require a near complete rewrite of large parts of the code.
