A user-defined function like


g(func f,x){return f(x);}


takes a 1-argument function as the first argument of g().  However currently, this first argument must be also a user-defined function.  A built-in function with the same signature cannot be passed as an argument.

E.g.


> f(x){return sin(x);}

> g(f,10pm4)
              -0.54402 +/-    3.35629
> g(sin,10pm4)
###Error: syntax error near token ',' in "g(sin,10.0pm4)"
