The default value of `org-export-babel-evaluate' is t. Having just crashed my Emacs session 5 times in a row trying to get a file containing a BEGIN_SRC emacs-lisp ... END_SRC *code example* to export to HTML...
I strongly feel it should default to nil. I also feel that "executable code block" and "quoted code example that I would like to display/export with pretty syntax highlighting" are two very different concepts, and should have different block names. eg #+BEGIN_EXEC for the executable blocks? or allow an argument to example blocks, eg "#+BEGIN_EXAMPLE python" ?
