May be you've got me wrong. I suggest to expose the function under
different names( aliases ) and than to create small function in
Python, which calls the desired one:
void foo( bool );
void foo( int );
def( "_foo_bool", (void *(bool) )( foo ) );
def( "_foo_int", (void *(int) )( foo ) );
Python code:
def foo( arg ):
if isinstance( arg, int ):
_foo_int( arg )
else:
_foo_bool( arg )
