It's not a bug, but it's a known ...situation. Function statements inside blocks are not a standard feature. They've had different behavior in different JS engines basically forever, and the last time we tried to change the behavior we gave up because it broke web sites.
If you tried that in strict mode code, it would be a SyntaxError. Programs shouldn't use function statements except (a) at toplevel, like your second example; (b) immediately inside the body of a function. -j _______________________________________________ dev-tech-js-engine-internals mailing list dev-tech-js-engine-internals@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-tech-js-engine-internals
