The easiest way to debug macros is to expand them by putting point at
the opening paren in a Lisp mode buffer and doing C-c RET (or C-c C-m).
You can do this recursively in the resultant Macroexpansion buffer, and
(soon?) will be able to expand forms in place.

You got it, the symbol you are generating is #:|bar-L-FOO| as
make-symbol doesn't intern its result, and you didn't normalize the case
of the string you gave to it anyway.  Some people like to
READ-FROM-STRING to get a reasonable symbol from a string; there are
other ways to get a reasonable symbol.
