Question on calling a specific function...

Hi all!
Is there a way to call a function where the function name is based on a variable?
Here is an example of what I would like to do:
Now I realize that the above example will give an error. Is there any way I can accomplish calling a funcion based on a variable without using switch of if statements?

Here is an example of what I would like to do:
function myNamespace::myFunction1(%myVar)
{
(some irrelevant code)
// here I want to call another function that is named with the value of %myVar
myNamespace::%myVar();
}Now I realize that the above example will give an error. Is there any way I can accomplish calling a funcion based on a variable without using switch of if statements?

%myNameSpace = "myNameSpace"; %myVar = "myVar"; %function = %myNameSpace @ "::" @ %myVar @ "();"; eval(%function);

Try it and see. I have not tried it.

If %myVar was a function pointer it may work with this syntax:function myNamespace::myFunction1( %myVar)
{
(some irrelevant code)
(%myVar)();
}
function myNamespace::myFunction2()
{
//...
}
// this calls myFunction1 setting %myVar as a function pointer
function someCallingFunction()
{
myNamespace::myFunction1( myNamespace::myFunction2);
}Try it and see. I have not tried it.

If you form it into a string you can simply eval() it :)
