Install and use pip on macOS without sudo / admin access

Most recently tested on macOS Sierra (10.12.6)

1. Download the installation script; curl https://bootstrap.pypa.io/get-pip.py -o ~/Downloads/get-pip.py
2. Run the installation, appending the --user flag; python ~/Downloads/get-pip.py --user. pip will be installed to ~/Library/Python/2.7/bin/pip
3. Make sure ~/Library/Python/2.7/bin is in your $PATH. For bash users, edit the PATH= line in ~/.bashrc to append the local Python path; ie. PATH=$PATH:~/Library/Python/2.7/bin. Apply the changes, source ~/.bashrc.
4. Use pip! Remember to append --user when installing modules; ie. pip install <package_name> --user

Should be work with 0.18

Destructuring(or pattern matching) is a way used to extract data from a data structure(tuple, list, record) that mirros the construction. Compare to other languages, Elm support much less destructuring but let's see what it got !

Tuple

myTuple = ("A", "B", "C")
myNestedTuple = ("A", "B", "C", ("X", "Y", "Z"))

Union Types

If Elm community is going to begin referring to "union types" instead of "algebraic data types" we should think about how that will work in practice. What discussions will we have? Will we find ourselves in awkward spots trying to explain things?

The following question/answer pairs simulate things I'd expect to see in a world of "union types". The pairs are grouped by what background I expect the questions to come from so we know the subtext. I have also added some meta comments in italic to explain my phrasing.

One thing to consider is that a lot of learners will not have a person to ask, so the path to arriving at these answers needs to be easy if you are just searching online.
