However, it is possible to simulate Unicode variable names to some extent by using the ''Var'' class in the above module which stores the names (which can be any valid string) in an internal map.
<syntaxhighlight lang="ecmascript">import "./trait" for Var
Var["Δ"] = 1
Var["Δ"] = Var["Δ"] + 1
System.print(Var["Δ"])</syntaxhighlight>
{{out}}
