This looks ok.

This looks right too, try this to show if they're installed

for k, v in pairs(wx.a2dRestrictionEngine) do print(k, v) end

or if you link the wxluasocket library, run this to show all of the
items in the lua _G (global) table.

wxlua.LuaStackDialog()

or run samples/bindings.wx.lua to look a little closer at the bindings.

and... check that they're actually installed, they should be in the
cpp file generated with the same name as the .i file where you
declared the %class a2dRestrictionEngine. Probably just grep for the
enums to see if they're there.
