Sorry for not replying so soon and thanks for the responces. However, this
doesn't seem to be a problem with discard since I can replace the discard to
echo to generate the same error.
proc add(x,y:int):int= x+y
echo add 1, 2 #=> Error: type mismatch: got <int literal(1)>
echo (add 1, 2) #=> Error: type mismatch: got <int literal(1)>

>(add(1,2))` since `add` takes two arguments. In reality, it seems to be
