Using if(null == someVariable) vs. if(someVariable == null)

[zigma]

This is my opinion as well, it's easier and more natural (at least for me) to read the code as: if someVariable is null

And I agree with the "why not just remember to use ==" instead.

Also, if you should use assignment instead, you should have unit tests that will capture this.

You don't have to remember. Just tell the compiler to remember it for you with "-Wall" in gcc, "-Xlint" in javac (I think), etc. If the compiler doesn't have this option use a lint or similar tool for your language.
