[nem-en] list operations priorities

[Kamil Skalski]

>        foo :: foo_list + bar :: bar_list

Right, I think it should parse as:

foo :: (foo_list + (bar :: bar_list))

so :: should have higher left priority than +'s right priority:
x + y :: z   --->    x + (y :: z)

the opposite case does not make much difference, but a bit of
performance gain with
x :: y + z   --->  x :: (y + z)   being better than   (x :: y) + z
