This is based on #21 so it may or may not merge cleanly.

Allows us to omit the do keyword when passing a zero arg function as the last argument. Moves Shrimp more towards Ruby, but without the insanity of instance_eval and method_missing - all variables and functions and scopes are still known at compile time.

## html templates
ribbit:
  head:
    title What up
    meta charset=UTF-8
    meta name=viewport content='width=device-width, initial-scale=1, viewport-fit=cover'
  end
end

list = tag ul class=list
ribbit:
  list:
    li border-bottom='1px solid black' one
    li two
    li three
  end
end

ribbit:      
  p class=container:
    h1 class=bright style='font-family: helvetica' Heya
    h2 man that is (b wild) (nospace) !
    p Double the fun.
  end
end

## tests
describe 'some tests':
  test something:
    expect (my call) | to-equal (my other call)
  end
end

## shell stuff
trap EXIT:
  file-handles | each do x: close x end
  echo Goodbye! 
end

## LOGO!
# Draw a square
repeat 4:
  forward 100
  right 90
end
    
# Move into position for the spiral
pen up
forward 150
pen down

# Draw a spiral
repeat 36:
  forward 10
  right 20
  forward 10
  right 20
end
