Hi Note that while CmdArgs 0.9 introduces a dependency on TH, it's only optional. If you disable the cabal flag "quotation" then it will build without template-haskell, so should still work fine on ARM.
I do have a dependency on template-haskell in the .cabal file, it's just under an if flag(quotation) branch, so isn't with the rest of the dependencies. Note that it isn't necessary to use template-haskell just because you use TemplateHaskell, but it would be rather challenging not to (you couldn't mention Q or any of the AST types).
