Make Coconut built-ins thread-safe

Especially given the presence of `concurrent_map`.

Add Coconut line numbers to MyPy output

Should automatically add Coconut line numbers to Python line numbers in `--mypy` output.

Coconut should compile to a temporary directory when --no-write is passed

Provides better error messages than not compiling the file at all, and allows for some degree of caching.

The code ``` func(head + [tail] match in list) ``` should be equivalent to ``` match [head] + tail in list: func(True) else: func(False) ``` with the exception that the...

e.g.: ```python def func(): do_stuff() return x do_more_stuff() ```

Add do-while loops

Possible syntaxes: ```python do: ... while cond ``` ```python do while cond: ... ``` ```python do: ... while: cond ``` Regardless, they should be compiled to: ```python while True: ......

Should make new exception subclasses just aliases for their superclass on older Python versions. See: search for “new in” in

Produce better assert error messages

We should do something similar to what pytest does with assert statements and provide a default error message for simple assert patterns with more information than the default message. For...

Use duck typing instead of abc checking in pattern matching

Should be significantly faster.
