type Mesh
var1
var2
..
Mesh() = new()
end
Will do the trick.
This will overwrite the default constructor, though.
If you want to have it back, the easiest way to do it would be this:
type Mesh
var1
var2
...
Mesh(varargs...) = new(varargs...)
end
now you can write:
m = Mesh()
m.var1 = ...
x = m.var2 # ERROR: undefined reference
