We propose an extension of Haskell's type class system with bstractions in the type language. Type inference for our extension relies on a novel constrained unification proce...

Linear Time Membership for a Class of XML Types with Interleaving and Counting
Regular Expressions (REs) form the basis of most XML type languages, such as DTDs, XML Schema types, and XDuce types (Thompson et al. 2004; Hosoya and Pierce 2003). In this contex...
