The following piece of code was generated with insert-kbd-macro

(fset 'foo
   [?\C-[ ?f ?\C-[ ?  ?\C-[ ?b ?\C-[ ?w ?\C-x ?o ?\C-x ?\C-v left left ?\C-@ 
?\C-r ?/ ?\C-m ?\C-w ?/ ?\C-y ?\C-[ ?y ?\C-m ?\C-x ?o])

If you put it into a file and load the file, the macro is available.
If you put point at the end of the macro definition and execute
C-x C-e (eval-last-sexp) this does not allow you to load the macro
(though eval-last-sexp doesn't throw an error, in the end the
macro foo is not available). If you put point inside the macro
definition and type C-M-x (eval-defun) it throws the error

(scan-error "Unbalanced parentheses" 1 145)

Yes, that should fix it.

Thanks, installed,
