Version defined after first use error

[John Simon]

Is there a simple way to do this without getting the "version defined after use" error?

version(Ansi) {
} else version(Unicode) {
} else {
    Version = Unicode;
}

I've resorted to this, but it seems hackish:

version(Ansi) {
    version = Ansi_ForReal;
} else version(Unicode) {
    version = Unicode_ForReal;
} else {
    Version = Unicode_ForReal;
}
