Raw Blame History

This document is a wishlist, its items aren't ordered in any way other than inline notes about dependency relations

Language

Typeclasses

Elixir-style protocols probably, only with n-ary dispatch which I saw in SICP-js

Rules

Placeholder constraints

Simultaneously match a pattern to a subexpression and give it a name to copy it over

Copy unique 1->1 names over by default to preserve their location info

STL

Command short-circuiting

Functions for each command type which destructure it and pass it to an Orchid callback

Runtime error handling

result? multipath cps utils? Not sure yet.

Pattern matching

This was the main trick in Orchid, still want to do it, still need to polish the language first

Macro error handling

Error tokens with rules to lift them out. Kinda depends on preservation of location info in rules to be really useful

Systems

Async

Join allows to run code when a tuple of pending events all resolve on the event poller

New: Network

Event-driven I/O with single-fire events and resubscription to relay backpressure to the OS. Initially TCP

New: Marshall

Serialization of Orchid data, including code, given customizable sets of serializable foreign items. Alternatively, code reflection so that all this can go in the STL
