In order to encourage std4 users to write verifiable code with arrays, we should aim to have a similar set of lemmas for arrays (https://github.com/leanprover/std4/blob/main/Std/Data/Array/Lemmas.lean…

The error messages from Lambdapi could be more informative.
Let us consider a simple example:
We want to define functions `fst` and `snd`:

The Cosmos-SDK's empty sdk.Dec (e.g. `sdk.Dec{}`) string form is represented as `""` (proof below).
However, FPDecimals' `from_str` method won't be able to convert this value.

This behaviour occurs in Idris 1.1.1 (development version 1.1.1-git:0b128884)
# Steps to reproduce
See the example code below.
I'm trying to program with monads over indexed types in the style …

The `instantiate2_address` helper inside cosmwasm-std is not accounting for the length of chain's contract addresses. Something like this would work:

Could you publish release 0.1.3.0 in Hackage? :-)
Trying to compile async-extras 0.1.2.0 with GHC 7.10.1 gives me the next error, but release 0.1.3.0 compiles solves it:

We want to use pointer equality as a performance optimization. For example, as a first check in `DecidableEq` instances: if the two arguments are pointer-equal, then we can immediately return `isTrue…

I often have manipulation that return a value, that I will both use in a single `manipulateParams` call, or sometimes in batch with `traversePrepared` - in this latter case, I very frequently do not w…
