The following example throws a syntax error: for (var i = 10; i >= 0; i--) function x(k) { return ++k; }; The following example does not: for (var i = 10; i >= 0; i--) { function x(k) { return ++k; }; } 82773 2 zwarich 2008-06-09 16:39:22 -0700 This is invalid syntax, according to the grammar in the ECMA spec. The body of a for loop is a Statement, and a FunctionDeclaration is not a Statement. Unless this is actually a compatibility issue, we should probably close this bug. 82774 3 ap 2008-06-09 16:57:54 -0700 Per the bug description, this sounds like a compatibility issue. 100095 4 zwarich 2008-11-24 16:16:08 -0800 *** This bug has been marked as a duplicate of 13790 ***
