#5 config() doesn't work with enums

[Andrew V. Adinetz]

config() doesn't work when the configuration variable is of enumeration type. Somehow it thinks that the variable is of integer type.

E.g., code like the following doesn't work as expected:

enum MyEnum { | A | B | C }
// ...
public Main() : void {
config a = MyEnum.A; // compiler thinks that a is integer
// ...
}

Looks like it's because resulting type is inserted as PExpr, not as type variable
