mozart - Why doesn't "for X in E1..E2;E3 do" work in Oz? -

-

i'm using mozart 2.0.0 , i'm following these docs: http://mozart.github.io/mozart-v1/doc-1.4.0/loop/node1.html#chapter.official

i'm guessing loop syntax has changed or something, because parse error when following documentation exactly:

x in e1..e2;e3

my attempt:

for x in 5..1;-1    {browse x} end

i got work more verbose syntax:

for x in ({length l};x > 0;x - 1)    {browse x} end

but first example seems way more readable , less error prone me. why doesn't work?

i did not test 2.0.0, in 1.4.0 works if replace - ~.

it's bit of unusual oz syntax: unary minus sign ~.

- used binary minus.
