It appears that you would like to pass the _name_ of a function (e.g. "f")
to a procedure (you use the name "myfunc") that would then evaluate this
function, at 0 or at some other set of values. You could do this with the
powerful but often-overlooked command "expr()".
The problem is that I do not believe that this would be valid inside a defined
_function_, as it would likely be considered to constitute a "side effect".
There is no real reason why it could not be accomplished with a _program_ named
"myfunc", however.
