Because functions are abstract values without convenient print
representations, implementing debuggers which support
higher-order code is a challenge.
We present an algorithm for statically specialising higher-order
functions and encoding higher-order values to allow printing.
We define our algorithm for a small functional language and
discuss how it may be extended to support sophisticated features of
modern functional programming languages. This research forms part of a
project (Supported by the Australian Research Council) to build a declarative debugger for Haskell, based primarily on source to
