MID_BLOCK_KEYWORD_REGEX =

Regex to match keywords that appear in the middle of a Ruby block with lowered indentation. If a block has been started using indentation, lowering the indentation with one of these won’t end the block. For example:

- if foo
  p yes!
- else
  p no!

The block is ended after %p no!, because else is a member of this array.

/(\d\.\d)?[\s]*([a-z]*)/i
