Expected an identifier and instead saw '/'.

Might be related:

var x;
if (x /= 2) { }


Expected ')' to match '(' from line 2 and instead saw '/='.

and bunch of other errors related to parsing error.

jugglinmike added a commit to jugglinmike/jshint that referenced this issue Oct 21, 2014

Added support for 'typeof /[a-z]/' and 'if (x /= 2) { ... }'
This commit fixes two things:

 1. We can now parse regular expressions preceded by 'typeof'.
 2. You can use *=, +=, etc. punctuators as conditions (you still
    need option 'boss' to turn off the warning though).

Closes jshintGH-657.
