Fun side project!

Legitimate usage of a comma within the block, e.g. `MVMuint64 a, b;` results in an avoidable compiler error otherwise. A change from my `semaphoverhaul` branch that I figure stands on...

Allows for `t/03-jvm/01-interop.t` to pass once more.

[JVM] Tune Java in response to nqp's (de)serialization rewrite

3

i.e. https://github.com/Raku/nqp/pull/777. Untested with a modern JDK, but should be doable with JDK 11.

- Introduce the nqp-ish, semaphore-ish, serializable `Counter` class for the MOP's sake. - Consider giving the JVM and JS backends atomicops. - Tests need adjustment due to the new symbol....

NativeCall needs a native char type

2

At the moment, if you need to use `CArray`/`Buf`/`Blob` to represent strings, people use `int8` as its type. This is bad. `char` can be unsigned, meaning any code that does...

[WIP] Enhance interop of generics, roles, and classes, Raku or nqp

2

If generic role and generic signature signature typechecks are busted, maybe generic typechecks are busted too. In giving generics the capacity to perform a typecheck in a way that plays...

Role group nonsignatured candidate typechecks go too deep

5

## The Problem A role is analogous to a routine. As such, it can be a multi of sorts if more than one role is declared with the same name:...

[JVM] Necromance a cheaper (de)serialization

3

This started as means of fixing https://github.com/rakudo/rakudo/issues/4952 for the next stretch of https://github.com/Raku/nqp/pull/776, but is kind of its own rabbit hole. The `hs_err` log produced by the failure in `CORE.d.setting`...

Make some enhancements to atomic integers

1

- Give nqp native refs to allow for usage of atomic ops in nqp. - Introduce a semaphore-like `Counter` that performs comparably. - I'm getting tired of writing every atomic...
