Hello!
I found a-b-c and a-b -c give different result. Anyone knows if this
is following the language specification or not?
a = 20
b = 19
c=3
pp! a-b -c
pp! a-b-c
gives
a - (b - c) # => 4
(a - b) - c # => -2
Wow. First case definitely looks like a bug. Any language where a - b - c would become a - (b - c)?
The problem is that a-b -c becomes a - (b - c) while a-b-c becomes (a - b) - c. Spaces shouldn’t change the result.
BTW
a = 20
b = 19
c=3
pp! a&-b &-c
pp! a&-b&-c
(a &- b) &- c # => -2
(a &- b) &- c # => -2
It’s a bug, please report it in GitHub.
It’s hard to fix.
Meh, it’s very easy to fix.

Great! I hope this will be included soon!
The language specification for these things is “Try it in Ruby. If you get a different result than Ruby then it’s a bug”.

Classic Ary 
I ended up closing the PR because I’m not sure it’s the best way to fix it.
You’ll have to hope someone else will fix it then.
