The most great and simple examples in README are images and blind programmers cant see this examples.

Why not use ``` tags to describe it?

The manual does not mention spawn_in_group and spawn_in_groups for spawning actors that immediately join a group as part of their construction.

Reamde says

matches([1])(
  (a, b,  tail)      => 'Will not match here',
  (a = 2, tail = []) => 'Will not match here',
  (a = 1, tail)      => 'Will match here, tail = []'
)

but

     let a = Z.matches([1])(
            (a = 1, tail) => {
                return 'a = 1, b = []'
            }
        );
        console.log("a");
        console.log(a); // u

User @codyschank had noticed that for small datasets, stumpy.stomp._stomp is faster than stumpy.stump. Here is some very rough timing calculations from my 2-core laptop:

    length       stomp       stump  stomp/stump   stump/stomp
0      128    0.006628    0.018066     0.366867      2.725782
1      256    0.

adapt_boost_variant.hpp is a good start, but it isn't enough to understand the concept.

E.g., what is subtype_cast_impl for? How Am I supposed to say that a reference to super-type should be cast to a reference to a sub-type?

Since we're going to rewrite the parser dramatically, we need some tests to make sure that the functionality of the math output is preserved

Right now some examples are displayed as images. Sight impaired users will not be able to enjoy these. A simple solution is to put the code as alt text. carbon.now.sh does this.

If you issue :help on the repl you get a list of available commands, among others. But the list is incomplete, e.g. :modules, :undeclare or :unimport are missing.

Currently gradoop contains multiple quick start examples. One within gradoop-examples module with a fitting wiki description and one within gradoop-quickstart (archetype). We should only maintain one example, preferably within the new quickstart module.

Refactor IntervalSym:

Many functions use a common "base" method:

• coth, csch,...
• sec, csc, tan, cot,...

Unify periodicity and function header usage.
Define common methods for duplicate codes.

Input code or something about issue background

I cannot run new benchmark test as described in https://github.com/bem/bem-xjst/blob/master/bench/README.md

node runner.js --rev1 <hash1> --rev2 <hash2> --bemjson 1000

Expected Behavior

Test should run and produce some results, because README file states that

dataPath and templatePath are optional

Actual Behavior

Error in

1. SyntaxWarning: "is not" with a literal

https://docs.python.org/3.8/whatsnew/3.8.html#changes-in-python-behavior

The compiler now produces a SyntaxWarning when identity checks (is and is not) are used with certain types of literals (e.g. strings, numbers). These can often work by accident in CPython, but are not guaranteed by the language spec. The warning advises users to use equality tes
