This paper discusses on the additional issues for the automatic inference of algebraic property-oriented specifications which arises because of interaction between laziness and logical variables in lazy functional logic languages.
We present an inference technique that overcomes these issues for the first-order fragment of the lazy functional logic language Curry. Our technique statically infers from the source code of a Curry program a specification which consists of a set of equations relating (nested) operation calls that have the same behavior. Our proposal is a (glass-box) semantics-based inference method which can guarantee, to some extent, the correctness of the inferred specification, differently from other (black-box) approaches based on testing techniques.
