I'm stupid - I didn't see the missing unquote. sorry :-)

Yes indeed, and since $ is already an "escape character" in make, it is
a great thing to use since . e.g. This might
be horrible but there should be less concern about it being
incompatible in some way:

foo$ bar$ biz$ baz

i.e. $<space>

Actually I hate that and I'm really arguing towards $[] or even $"".
