Watching like a hawk is always good! ;)

In addition to that, I would recommend to use 'trace' and 'debug'. Especially
'trace' is more useful than it may seem, letting you monitor your whole
program's behavior selectively. Individual functions can be single-stepped with
'debug', or by manually setting a breakpoint '!' with 'edit' or in the source
code.

Just move '(let Some_sym ...' up.

I think you mean

   (let (A 1  B 2)
      ... )
