Using traits get a list of methods and filter out the member vars.

[Adam D. Ruppe]

Something along the lines of

static if(__traits(compiles, __traits(getMember, Foo, member))
    static if(is(__traits(getMember, Foo, member) == function)) {
      // use it
    }


The __traits(compiles, ...) is my go-to thingy for filtering out 
random errors.
