If I run

using FFTA
a = rand(ComplexF64, 128)
p = FFTA.plan_fft(a)
typeof(p)

I get

FFTA.FFTAPlan_cx{ComplexF64, 1}

but if I run

using FFTA, FFTW
a = rand(ComplexF64, 128)
p = FFTA.plan_fft(a)
typeof(p)

I get

FFTW.cFFTWPlan{ComplexF64, -1, false, 1, Tuple{Int64}}

This causes subtle bugs in my code, and presumably is not what is intended? Is this a misunderstanding on my part (on how Julia works) or can this be fixed somehow (in either FFTA, FFTW or AbstractFFTs)?
