>             Project: Groovy
>          Issue Type: Bug
>          Components: Static Type Checker
>    Affects Versions: 2.4.3

> I wanted to use the power operator to set a static constant field:
> {code}
> public static final int DIGITS_IN_CODE = 4
> static final int mod = 10 ** DIGITS_IN_CODE
> {code}
> This results in a compile-time exception when used with {{@CompileStatic}}:
> {code}
> Groovy:[Static type checking] - Cannot assign value of type java.lang.Number to variable of type int
> {code}
> Replacing the symbolic constant with just {{10 ** 4}} produces the same bug. It appears that power expressions are not getting resolved until runtime even if they're compile-time constant expressions.
