An effort has been made to try to make this package as portable as possible.
That's a noble goal for libraries!
However, because it uses the ST monad and the mtl-2 package it can't be H98 nor H2010. However, it only uses the following common extensions which should be well supported[3]:
Rank2Types MultiParamTypeClasses FunctionalDependencies -- Alas, necessary for type inference FlexibleContexts -- Necessary for practical use of MPTCs FlexibleInstances -- Necessary for practical use of MPTCs UndecidableInstances -- For Show instances due to two-level types
Out of these FunctionalDependencies seems to be the most exotic (even in GHC-oriented development there has been some shift towards type families, it seems). Is it used only for mtl stuff (and thus can be replaced by 'transformers' + some lifts), or is it necessary for your own API? -- Roman I. Cheplyaka :: http://ro-che.info/
