I realize that it's impossible to know which function to call from f(5) in the code I posted, but I get an error even if remove the default value for the boolean in the second call, in which case it's pretty clear which function I am calling. Any thoughts? Thanks. On Fri, Apr 17, 2009 at 5:25 PM, A B <python6009@gmail.com> wrote:
Does anyone know why the following sample fails (it was adapted from the boost overloading example) and how to do this correctly. Thanks in advance.
