CCing to Roel (base-unicode-symbols maintainer)

Roel, according to [1] base-unicode-symbols- is still having
trouble with:

[12 of 12] Compiling Control.Arrow.Unicode ( Control/Arrow/Unicode.hs,
dist/build/Control/Arrow/Unicode.o )
Control/Arrow/Unicode.hs:88:6: Not in scope: `>>>'
Control/Arrow/Unicode.hs:96:6: Not in scope: `<<<'

Can you fix it?
