ZuriHac 2016 - Low-level Haskell: An Interactive Tour Through the STG

An interactive tour through the Spineless Tagless G-machine, the intermediate language that runs Haskell programs, revealing the low-level programming concepts and optimizations that power the language.

Key takeaways

Low-level Haskell programming involves working with the STG (Spineless Tagless G-machine) intermediate language.
The STG is an abstract machine that is used to run Haskell programs, and it is not directly related to the final output of a Haskell program.
The STG is used to optimize the execution of Haskell programs, and it is the final target of the GHC compiler.
In the STG, functions are represented as thunks, which are functions that have not been evaluated yet.
The STG is a stack-based language, which means that it uses a stack to store data and functions.
The STG has a garbage collector that is used to manage memory and eliminate unreachable code.
The STG is a purely functional programming language, and it does not support mutable state or side effects.
The STG is used to implement lazy evaluation, which means that expressions are evaluated only when their value is actually needed.
The STG is used to implement strict evaluation, which means that expressions are evaluated immediately when they are defined.
The STG is used to implement pattern matching, which is a powerful feature of Haskell that allows for concise and expressive code.
The STG is used to implement lazy evaluation, which means that expressions are evaluated only when their value is actually needed.
The STG is used to implement strict evaluation, which means that expressions are evaluated immediately when they are defined.
The STG is used to implement pattern matching, which is a powerful feature of Haskell that allows for concise and expressive code.
The STG is used to implement list comprehensions, which are a concise way of defining lists in Haskell.
The STG is used to implement anonymous functions, which are functions that are defined without a name.
The STG is used to implement lambda functions, which are functions that are defined using the lambda calculus.
The STG is used to implement recursive functions, which are functions that call themselves.
The STG is used to implement higher-order functions, which are functions that take other functions as arguments.
The STG is used to implement closure, which is a function that has access to its own scope.
