Return and Break

As-of v0.69.0 we have basic return and break support. These work pretty-much everywhere you'd expect except in comprehensions. Currently there is no support for return or break in comprehensions. However, return works in if-statements, while-statements and function-bodies. break works in while statements and has functionality beyond normal JavaScript: it can take a value to return.

Examples:

count = 0
stopAt = 50
while count < 100
  break if count == stopAt

(stopEarly) ->
  return true if stopEarly
  foo()

Break

count = 0
stopAt = 50
a = while count < 100
  break 123 if count == stopAt
# a == 123
