At the moment, there is no alternative method: you have to define
geoemtrical entities supporting the mesh (lines for 1D meshes, surfaces
for 2D meshes, etc.)... You may try to automate things with loops and
arrays of variables:

For i In {start:stop}
  l[i] = newreg;
  Line(l[i]) = {i,i+1};
EndFor

etc.
