no, eval'ing isn't particularly good cuz it'll truely mangle arrays (it'll
actually pass the string "Array" to the function if it hits an array).

The problem is in your syntax. Why not try:

   $foo = new bdd;
   $bar = bdd_function;
   $foo->{$bar}("foo bar !");

In the original example, you are basically assigning the contents of the
variable $foo->bdd_function to the variable $bar. If you really wanna try
the original way, you could try something like:

   $foo = new bdd;
   $bar = "\$foo->bdd_function";
   $bar("foo bar !");

but I have no idea if that'll work.
