Invokes the named function and returns a mirror on the result.
Let o be the object reflected by this mirror, let f be the simple name
of the member denoted by memberName, let a1, ..., an be the elements
of positionalArguments, let k1, ..., km be the identifiers denoted by
the elements of namedArguments.keys, and let v1, ..., vm be the
elements of namedArguments.values. Then this method will perform the
method invocation o.f(a1, ..., an, k1: v1, ..., km: vm) in a scope that
has access to the private members of o (if o is a class or library) or
the private members of the class of o (otherwise).
If the invocation returns a result r, this method returns the result of calling reflect(r).
If the invocation causes a compilation error the effect is the same as if a non-reflective compilation error had been encountered.
If the invocation throws an exception e (that it does not catch), this method throws e.
