Running "./configure && make" gives the following error Makefile:966 ***missing separator. Stop

I don't know where I should report this issue, but I'm getting a haskell-lsp error whenever I try to execute an action. For example: * When I try to change...

This is probably not a bug, but I found the behavior unintuitive when working on the source code that generated the constraint. Maybe we can improve the implementation of scrape...

The only way we have to relate types is via subtyping. This plays poorly with invariant type constructors because we must apply subtyping both ways. This is especially bad if...

The following is crashing with ``` error: internal compiler error: crates/flux-middle/src/rty/projections.rs:54:13: failed to resolve `AliasTy { args: [F, (T,)], refine_args: [], def_id: DefId(2:3046 ~ core[8a68]::ops::function::FnOnce::Output) }` in DefId(0:34 ~ flux_examples[6cad]::enums::option::{impl#0}::map)...

This is related to #671, but I feel we will need a couple of extra things to make this code work. ```rust #[flux::refined_by(ring_len: int, head: int, tail: int)] #[flux::invariant(0 <...

```rust #[flux::assoc(fn eval(x: int) -> int)] trait MyTrait { } impl MyTrait for i32 { } #[flux::sig(fn(x: i32) -> i32[::eval(x)])] fn test00(x: i32) -> i32 { todo!() } ``` ```...
