    Fix (and test) for SourceForge bug 1161624: erroneous rejection of
    	foo = proc x -> arr (\y -> y-1) -< x
    Now open a new level for the left side of -<, so that variables bound
    in the proc are illegal, but variables bound in the expression are OK.
    Note that the levels gimmick doesn't really implement holes in the
    scope: it rules out nasty obfuscations like
    	foo x = proc x -> arr (\y -> x-1) -< x
    Also added the same treatment to the head of a `form', where it was
    (for STABLE)
