Attempting to bind values to reserved name should trigger a warning

I have wasted a disgusting amount of time only to realize that row is a reserved keyword. I basically had something like this compiled without warning, which does not even make any sense because row here is shadowed by the reserved name anyways.

for row in bson.inner : HorizontalBox {
    key := Text {
        text: row.key;
    }
    value := Text {
        text: row.value;
    }
}

True. We should probably error out if re-using reserved names.
I created issue #739 to track that.
Thanks for the report.
