DataFrames.jl Version 1.5.0.
Julia Version 1.6.1
When one or more columns in an array are of type bitvector, dropmissing! will fail.
The issue appears to be caused at line 922 of dataframe.jl …

It would be neat if this worked:
```
let x : bits(5) = 0b1 @ zeros();
```
Unfortunately it doesn't currently:
```
14 | let x : bits(5) = 0b1 @ zeros();

Currently the CppTranspiler (which converts DSLX types to C++ types) generates unusable C++ code for >64 bit types. It compiles but will not give the right result. It is actually convenient that it _d…

In input-output-hk/ouroboros-network#1191, the primary index is a dense index that stores the offset in the secondary index file for each slot. If the slot is empty, the offset of the slot before it i…

**Describe the bug**
Use of division on bitvectors quickly leads to unprovable VCs.
It would be good to understand if the support of division/remainder bitvector operation will be improved in the …

A `ConstrRepr` uses two fields to encode a _mask_ and a _value_ to encode constructor bits. For example:
```haskell
ConstrRepr 'A 0b110011 0b1010 []
```
which would mean: take the four bits in…

If `useSymbolicArrays` is turned on, What4 will still back a constant array with a lambda function, which can generate invalid yices input:

There are at least two things broken with the `arrays` example in `heapster-saw/examples`.

I'm experimenting with adjusting a Z3-based tool to produce bitvector encodings of its problems rather than integer encodings. This is producing surprising performance regressions.
The tool I'm wor…
