It also works correctly if the exponent is a complex array:
IDL> w= EXP( -COMPLEX(0.0,1.0)*(2.0*!pi)/16)
IDL> print,w
( 0.923880, -0.382683)
IDL> p=[1,2,3]
IDL> print,w^p
( 0.923880, -0.382683)( 0.707107, -0.707107)
( 0.382683, -0.923880)
IDL> p=1.0*p
IDL> print,w^p
( 0.857090, -0.00000)( 0.857090, -0.00000)
( 0.857090, -0.00000)IDL> w= EXP( -COMPLEX(0.0,1.0)*(2.0*!pi)/16)
IDL> print,w
( 0.923880, -0.382683)
IDL> p=[1,2,3]
IDL> print,w^p
( 0.923880, -0.382683)( 0.707107, -0.707107)
( 0.382683, -0.923880)
IDL> p=1.0*p
IDL> print,w^p
( 0.857090, -0.00000)( 0.857090, -0.00000)
( 0.857090, -0.00000)
IDL> p=complex(1.,0.)*p
IDL> print,w^p
( 0.923880, -0.382683)( 0.707107, -0.707107)
( 0.382683, -0.923880)

IDL> p=complex(1.,0.)*p
IDL> print,w^p
( 0.923880, -0.382683)( 0.707107, -0.707107)
( 0.382683, -0.923880)

Truly bizarre.
