Haskell 2010: Difference between revisions

Latest revision as of 18:16, 12 March 2025

Introduction

At the 1997 Haskell Workshop in Amsterdam, it was decided that a stable variant of Haskell was needed; this became “Haskell 98” and was published in February 1999. The ﬁxing of minor bugs led to the Revised Haskell 98 Report in 2002.
The Haskell Prime effort was thus conceived as a relatively conservative extension of Haskell 98 [...]
After several years exploring the design space, it was decided that a single monolithic revision of the language was too large a task, and the best way to make progress was to evolve the language in small incremental steps, each revision integrating only a small number of well-understood extensions and changes. Haskell 2010 is the first revision to be created in this way [...]

Preface, Haskell 2010 Language Report (online).
