if(a) {
function b(){ }
}
A block can contain statements. A statement can't start with the
function keyword.
Mozilla's Core JavaScript guide explains that of |b| should be
evaluated as a functionExpression, but this isn't right.

What should the above code do?
Should it be:
if(a) {
(function b(){ });
}
SHould it be a function declaration, just like a variable statement?
if(a) {
var b;
}
Spidermonkey treats |b| as a function declaration as a statement (example).
No imlementations I know throw a SyntaxError; instead, the behavior is
implementation-specific.
