Quoting Miles Bader <address@hidden>:

M-: (setq foo 1) RET
M-: (let ((foo 2)) (error "foo")) RET
M-: foo   ---> 2

After an error, the `let' form gets exited too, so the global variable
isn't rebound to its original value.

If that's really happening, it's a very serious bug in `let'.
_Huge_ amounts of code depends on let dealing with errors correctly...

However when I tried to reproduce it using your example above, I couldn't
Are you sure your final test evaluation of `foo" above isn't done while
the debugger's recursive edit (with backtrace) is still active?  While
in that recursive edit, you're still actually "inside" the let context.

Whoops, you're right.  I have debug-on-error on, and forgot to do
M-x top level after the error.

Sorry for the noise.
