Hi Martin - No: it's just that we removed this way of creating 
geometries from the old parser. All the new stuff will be driven by Lua. 
This is what it will look like, more or less (in a ".lua" file):

g = GModel()
v1 = g:addVertex(0, 0, 0, 1)
v2 = g:addVertex(1, 0, 0, 1)
e1 = g:addLine(v1, v2)
f1 = g:extrude(e1, {0,0,0}, {0,1,0})
r1 = g:extrude(f1, {0,0,0}, {0,0,1})
r1 = g:revolve(f1, {-.1,0,0}, {-.1,1,0}, 3.1415 / 2)
