I have some script with a trouble.

p(100 - (1 + 2 + 3 + 4))

=> 90

ok

p(100 - (1 +
2 +
3 +
4))

=> 90

ok

p(100 - (1

• 2
• 3
• 4))

=> 96

BUT it should be 90

If I run the script I will get

$ rvm use 1.9.3

$ ruby -v
ruby 1.9.3p484 (2013-11-22 revision 43786) [i686-linux]

Ooops. How can I fix the layout?

[Victor (Victor Daev)]

p(100 - (1 + 2 + 3 + 4))
# => 90
# ok

p(100 - (1 +
2 +
3 +
4))
# => 90
# ok

p(100 - (1
+ 2
+ 3
+ 4))
# => 96
# BUT it should be 90

I think this issue is not a bug.

p(100 - (1

• 2
• 3
• 4))

is interpreted as

p(100-(1;+2;+3;+4))

Is it ok? How about "the Principle of Least Surprise"?
