Pattern matching with variable assignment (the priority of `in` operator)
I wrote this code:
n = 0 ret = n in 99 p ret
false but was
0 (truthy value).
I had to write like this:
n = 0 ret = (n in 99) p ret #=> false
However, I would like to write
ret = n in 99 because it is more natural for me, and I am afraid many people might mistake like me. Could you reconsider the priority of

We have discussed about in-line pattern matching and made a decision that it should cause an exception instead of returning false. So this issue will disappear.
We might need to talk about the precedence for e.g.
a = n in 99 rescue nil.
