duplicate active loop label

Why this fires¶

Two nested, simultaneously active loops declare the same label. A labelled exit would be ambiguous to readers even though the innermost declaration could be selected mechanically.

:scan loop {
    :scan while ready() { // error[TE226]
        break
    }
}

Fix it¶

Rename one label so every active target is unique.

:scan loop {
    :retry while ready() {
        break :scan
    }
}
