  This is not the whole story. #local declarations are not seen outside the
macro, although the value of a locally declared identifier can be passed
outside the macro.
  This example shows how this #local behaviour is seen in practice:

#macro MyMacro()
  #local MyVar = 5;
#end

#declare MyVar = 2;
MyMacro()
#debug str(MyVar,0,0) // 'MyVar' is still 2 here!
