Would something along the lines of::

    foo = e(x,y)::
        S

Work?  The double colons (assuming the parser can handle this; don't see
why not but I am knowledge of parsers amounts to squat) would allow for an
obvious differentiation between a pseudo inline block that is being used
in an assignment statement and where a single colon is normally used.
And since there is no keyword here specifically delineating that it is a
define or something it kind of lets it look like a call on e which is sort
of what it is doing.  A stretch, I know, but hey, every bit helps.  =)
