PropertyHandle :: ExecuteExpression - Execute expression
Execute expression allows running in line expressions or persistent expressions. When running an in line expression containing one or more statements, the expression must be enclosed in {}. The result is returned as property handle, which allows an expression returning elementary or complex instances as well as instance collections.
When calling a persistent expression stored in the resource database the expression name must be preceded by the scope declarator (::).
"if (1>2) Print('true')" // in line expression
::GetTotalIncome(2004) // persistent expression
