Open Points

• Right now it is not possible to use Complex numbers without units, since the created method dispatches on Real instead of Number, this was done, because Unitful.Quantity is also a subtype of Number and therefore the method could be called with a quantity of the wrong dimension. It would be possible to add another check for each variable, but for now the numerical values are restricted to Real.

• During the creating of the default constructor for a struct, the complete struct definition is evaluated in the scope of the macro to extract the fieldnames. I am not sure about the consequences this might have, so there might be a better way to extract the fieldnames from the Expr

• Currently the @optionalunits macro only works with the function f(x) end syntax, the shorthand form f(x)= is not yet supported!
