If you use a let within the init-form of an outer let, the result is invalid javascript code.
Here is a simplified example:
(ps (let ((x (let ((y (a))) (b) y))) (1+ x)))
==>
"(function () { var y; var x = (y = a(), (b(), y)); return x + 1; })();"
Not that I would normally write such code, but the inner "let" was generated by a macro. And many macros use "let"* *with gensyms. In my case, the macro used "ps-once-only".
