Description

The Data.Complex.phase function contains this line: phase (0 :+ 0) = 0 -- SLPJ July 97 from John Peterson

This is not necessary since atan2 (invoked on the following line) is defined such that it returns 0 in this case already.

Since it's not GHC-specific (see Ian's comment above), close as invalid?
