Patternr - experiment with pattern matching

This looks like a really neat project! I think it would be really helpful to have a couple links that will prefix an example pattern so users can easily see working examples of supported patterns.

Also it would be good if more complex patterns were accepted:

And a minor improvement would be to change “Incorrect Pattern” to “Invalid Pattern”. Incorrect doesn’t really match because you don’t know the users intention.

But overall great job!

Hi, here are some suggestions

1. case 1..2 does not work

2. case 1 when x when is_integer(x) -> does not work either (maybe guards are not supported yet)

3. I would add an end to the the template

case [ TERM ] do
  [ PATTERN ] -> ...
end

That is the Phoenix color
