Philip Wadler. A Complement to Blame. In 1st Summit on Advances in Programming Languages (SNAPL 2015). Leibniz International Proceedings in Informatics (LIPIcs), Volume 32, pp. 309-320, Schloss Dagstuhl – Leibniz-Zentrum für Informatik (2015) https://doi.org/10.4230/LIPIcs.SNAPL.2015.309

Abstract

Contracts, gradual typing, and hybrid typing all permit less-precisely typed and more-precisely typed code to interact.  Blame calculus encompasses these, and guarantees blame safety: blame for type errors always lays with less-precisely typed code. This paper serves as a complement to the literature on blame calculus: it elaborates on motivation, comments on the reception of the work, critiques some work for not properly attending to blame, and looks forward to applications.  No knowledge of contracts, gradual typing, hybrid typing, or blame calculus is assumed.
