Description
Steps to reproduce
esprima.parseScript('if (foo) { return 5; } else { return 6; }');
I would like to be able to successfully parse this without an Illegal return statement error, but also without using {tolerant: true} (which comes with additional baggage I don't want).
See also: espree's globalReturn flag.
