But a is defintiely a variable, while b may be a function call.
In a = b if b, you compute the function twice.
In a = b or a, you compute the function only once.

Best I could come up with just now was:
a = b || a
a = b if b
Not really DRYer :), you just repeat a instead of b

Methods that are expensive and/or have side effects should probably
not be named b
