You could define your own feval:
feval(fn_str, args...) = eval(parse(fn_str))(args...)
This has the advantage of accepting anonymous functions and multiple
arguments if necessary:
julia> feval("sin",5.0)
-0.9589242746631385
julia> fn_str = "a_plus_b(a,b) = a + b"
"a_plus_b(a,b) = a + b"
julia> feval(fn_str,2,3)
5
