* Create "babel-helper-wrap-function" It contains the logic to wrap a function inside a call expression. It was part of the "babel-helper-remap-async-to-generator" package, but it is needed to transpile "function.sent" * Create "babel-transform-function-sent" It transforms the "function.sent" meta property by replacing it with "yield" and making the generator ignore the first ".next()" call. * "function.sent" is the last value passed to .next(), not the first one * Disable exec tests on old node * Fix flow error * Add "transform-function-sent" to "stage-2" preset * Do every trasformation in one traversal * Test for "yield function.sent" * [skip ci] * Fix some typos [skip ci]
