Converting an object to a string has a very defined path in
JavaScript, toString is called. Perhaps the spec should mention
toString.
Marking the query as bogus seems wrong, since the JavaScript language
is very lenient about types and implicit type conversions when needed.
Implicit conversion to strings is what any proficient JavaScript
author would expect to happen. I don't see any reason to make the
storage spec behave differently.

In other words, if the type of the argument is not null, string,

As an alternative, I would like to present a slightly different
approach: if, during step 3 of the executeSql algorithm
(http://www.whatwg.org/specs/web-apps/current-work/multipage/section-sql.html#executing
),
an argument is found to be unpalatable for the underlying database
implementation, the statement is marked bogus.
Though a bit more stringent than the implicit conversion, this
approach explicitly prevents any subtle coercion bugs and will
probably lead to more debuggable code.
