If it's an issue - I'll change it. It's just my habit to write conditions in Yoda style (thanks @parkr - never knew how to refer this style). For me it seems easier to parse mentally this style:

``` ruby
if 0 < (port = server.port_number)
# vs
if (port = server.port_number) > 0
```

And it makes sure that you'll get an error if you'll mistype `==` condition an will write `if 5 = port` accidentally.
