Call a function with variable function name

Question

Hey guys,
I have a func_table which maintains function names (each one makes reference to a dynamically generated stored function)
I need to make a procedure that calls the functions in that table one by one using its name retrieved from SELECT func_name FROM func_table;
Thanks

That dynamic code is 99% of the time wrong. That dynamic code opens securities hole for code injection. That dynamic code often results in severe performance penalties as the coder is clueless about what the Oracle Shared Pool is about. And so on...
As for a basic procedure template to do this - assuming all functions get the same parameter as input and that all functions returns the same data type:
create or replace procedure FooBarFunctions( paramVal number ) is
  .. variables and types and cursor definitions..
begin
  for c in (
    select function_name from my_fubar_functions order by function_order
  ) loop
      plsqlBlock := 'begin :result := '||c.function_name||'( param => :p ); end;';
      execute immediate plsqlBlock using out funcResult, in paramVal;
      .. do something with funcResult ..
  end loop;
  .. more code..
end;
{code}
Looks not like a sensible approach though - and begs for justification as to why this approach is needed. What justification do you have?
