Pattern: Invalid multiple comparison
Issue: -
In math and Python, you can use x < y < z style comparison to compare
multiple value. However, you can't use the comparison in Ruby. However,
the comparison is not syntax error. This rule checks the bad usage of
comparison operators.
# bad
x < y < z
10 <= x <= 20# good
x < y && y < z
10 <= x && x <= 20
