Make your code fly


Merlin is a dynamically and strongly typed programming language written in Rust. Merlin's threading system empowers programmers to write powerful code that leverages concurrency - regardless of whether your system has atomics.

Merlin uses Rust's atomic data types to remove the need for a GIL without sacrificing performance.

In addition, it has a register-based interpreter (like CPUs) which has large performance advantages over the Python stack-based interpreter that is simpler and needs to shuffle a lot of memory around.

### Current comparison to Python:

With this code:

```Python

a=1

b=2

a+b

a+b

a+b

```

Total execution time:

Merlin 1.3 (release): 20 ns

`./merlin program.me -t 10000`

Python 3.10.6: 54.9 ns 

`python3 -m timeit -c "a=1;b=2;a+b;a+b;a+b"`

Merlin is: 2.75x **faster**

***

With this code:

```Python

a=1

b=2

a+b

a+b

a+b

a+b

a+b

a+b

```

Total execution time:

Merlin 1.3 (release): 57.86 ns

`./merlin program.me -t 10000`

Python 3.10.6: 103 ns 

`python3 -m timeit -c "a=1;b=2;a+b;a+b;a+b;a+b;a+b;a+b"`

Merlin is: 1.78x **faster**

***

Merlin 1.3: 2.89x slower for 2x more.

Python 3.10.6: 1.87x slower for 2x more.

## Installation
