Re: [sc-users] using a custom function in classes

[James Harkins <jamshark70@xxxxxxxxx>]

The only way (I'm fairly sure) is to pass the function into the method
as an argument.

Your function exists outside the lexical scope of the class, so there
is no way for it to know about the func magically.

calc { arg x, func;
...
}

myThing.calc(100, myFactorialFunction)
