Avoid reexporting dependencies?

FastTransforms.jl/src/FastTransforms.jl

Lines 6 to 8 in d7be08c

	@reexport using AbstractFFTs
	@reexport using FFTW
	@reexport using GenericFFT

This adds additional names to the user's namespace, as well as makes this package brittle. Perhaps it's better to avoid re-exporting them, and ask users to import them as required.
