We're happy to have Jason Ganetsky, tech lead of storage for Google Cloud Pub/Sub, presenting on Making a Fast Curry: Push/Enter vs. Eval/Apply for Higher-order Languages (http://community.haskell.org/~simonmar/papers/evalapplyjfp06.pdf) by Simon Marlow and Simon Peyton Jones.
Intro
Higher-order languages that encourage currying are typically implemented using one of two basic evaluation models: push/enter or eval/apply. Implementors use their intuition and qualitative judgements to choose one model or the other. Our goal in this paper is to provide, for the first time, a more substantial basis for this choice, based on our qualitative and quantitative experience of implementing both models in a state-of-the-art compiler for Haskell.
Our conclusion is simple, and contradicts our initial intuition: compiled implementations should use eval/apply.
Bio
Jason Ganetsky (https://about.me/jasonganetsky) (@ganetsky (https://twitter.com/ganetsky)) is a software engineer at Google. He is tech lead of storage for Google Cloud Pub/Sub (https://cloud.google.com/pubsub/docs). Prior to working at Google, Jason worked at various startups in NYC, and was briefly enrolled in a Computer Science PhD program at Carnegie Mellon. It was that brief stint that sparked the beginning of Jason's lifelong love of functional programming and type systems.
