I love #ocalm.
it has many superpowers
- #soundcomplete and #strong #typesystem with #typeinference
- #algebraiceffects
- #algebraicdatatypes
- #GADT
- #patternmatching
- pragmatic by default #immutanbility
- pragmatic and optional laziness
it gives confidence and correctness via type system and compiles
#ocaml shape languages like #scala and #rust also #Fsharp is just reincarnation of ocaml for dotnet
Melange brings this power to #reactnative developers.

We explore the design and implementation of Frank, a strict functional programming language with a bidirectional effect type system designed from the ground up around a novel variant of Plotkin and Pretnar's effect handler abstraction. Effect handlers provide an abstraction for modular effectful programming: a handler acts as an interpreter for a collection of commands whose interfaces are statically tracked by the type system. However, Frank eliminates the need for an additional effect handling construct by generalising the basic mechanism of functional abstraction itself. A function is simply the special case of a Frank operator that interprets no commands. Moreover, Frank's operators can be multihandlers which simultaneously interpret commands from several sources at once, without disturbing the direct style of functional programming with values. Effect typing in Frank employs a novel form of effect polymorphism which avoid mentioning effect variables in source code. This is achieved by propagating an ambient ability inwards, rather than accumulating unions of potential effects outwards. We introduce Frank by example, and then give a formal account of the Frank type system and its semantics. We introduce Core Frank by elaborating Frank operators into functions, case expressions, and unary handlers, and then give a sound small-step operational semantics for Core Frank. Programming with effects and handlers is in its infancy. We contribute an exploration of future possibilities, particularly in combination with other forms of rich type system.
Programming Languages DelftMaster thesis by Olek Wolska:
Towards Modular Language Semantics of WebDSL: A Case Study of Using Algebraic Effects in Haskell for Language Specification
"We adapt the algebraic effects and handlers approach [...] to create a modular denotational semantics model of WebDSL [...] that allows us to distinguish between effects raised by different components of the language."
