Depends on your goals / constraints. From a performance standpoint, the attribute lookups can often dwarf the overhead of an extra assignment.

I'm speaking solely from a developer experience perspective.

We're talking about cases where the expression is only used once, so the assignment is free/can be trivially inlined, and the attribute lookups are also only used once so there is nothing saved by creating a temporary for them.
