var <-convert: name -> var

Converts name to var from @variables.

In older versions of PCE @arg1, etc. where special objects. The x, y, etc. variables appearing in formulas for class handle and class spatial where other special features. In the current implementation class var takes care of all these cases. To keep the name-as-variable as used in formulas compatible we had to introduce the name conversion mechanism.
