@fullmoon.id takes us on a journey with Grace: from a typed interpreted functional programming language to prompt-engineering pipelines; with thoughts on cunning LLMs, agentic coding, SE excellence (the importance of ownership, typing the code out, and holistic knowledge) youtu.be/lTEP0zrjPwY

Beyond agentic coding with Grace, inspiring nice programming language

I wrote a post about a cool feature that's actually been in Grace for a while: type-safe eval This feature also powers Grace's support for type-safe dynamic imports, a feature which had long been requested in Dhall haskellforall.com/2026/01/type...

You can now load Grace functions as Haskell functions

$ghci> increment <- load (Code "(input)" "\\x -> x + 1") :: IO (Natural -> IO Natural) ghci> increment 3 4 ghci> generateNumbers <- load (Code "(input)" "\\key -> prompt{ key }") :: IO (Key -> IO [Natural]) ghci> generateNumbers key [0,1,2,3,4,5,6,7,8,9] ghci> generateNumbers key [1,2,3,4,5,6,7,8,9,10]$

One cursed/blessed Grace feature that's not well known is that Grace supports type-safe eval

$# Grace supports "eval", meaning that you can import code from strings (even # dynamic strings which depend on values in scope) and yet everything is still # type-checked correctly and the compiler infers that the expression's type is: # # Natural -> Natural let one = 1 in import read "\\x -> x + ${show one}"$

I got a makeover

$Screenshot of Grace browser demo with the following program: \{ "OpenAI API key" } -> import prompt{ key: .'OpenAI API key' } : { "Job Description": Text } -> { "Is Finance?": Bool, "Rationale": Text } *** Inputs: OpenAI API key: ******* Job Description: artist Outputs: Is Finance?: false Rationale: The brief title 'artist' describes a creative/artistic role and does not indicate responsibilities related to accounting, financial analysis, investment, or other finance functions.$
