* Try to detect when `from` in a `for` loop declaration is an identifier, not a keyword
* Handle destructured arrays
* from as a destructured, aliased object variable name in a for loop declaration
* Added support for for-from loop, see #3832
* for-from: remove extra newline and add support for ranges
* for-from: tidy up the lexer
* for-from: add support for patterns
* for-from: fix bad alignment
* for-from: add two more tests
* for-from: fix test "for-from loops over generators"
See explanation here: https://github.com/jashkenas/coffeescript/pull/4306#issuecomment-257066877
* for-from: delete leftover console.log
* Refactor the big `if` block in the lexer to be as minimal a change from `master` as we can get away with
* Cleanup to make more idiomatic, remove trailing whitespace, minor performance improvements
* for-from: move code from one file to another
* for-from: clean up whitespace
* for-from: lexer bikeshedding
* Move "own is not supported in for-from loops" test into error_messages.coffee; improve error message so that "own" is underlined
* Revert unnecessary changes, to minimize the lines of code modified by this PR
This breaks compatibility with
->
yield for i in [1..3]
i * 2
and
->
yield
i * 2
yield's behaviour now mirrors that of return in that it can be used stand alone as well as with expressions. Thus, it currently also inherits the above limitations.
