The diamond operator doesn't like compound variables; but you can work around that by using its function form: readline. This works fine:

while( readline( $Some{compound}{variable}[1] ) ) {
    ...
}

    I ran into this a few months ago as I wanted to create a dictionary of handles, but somehow, never came across readline. I'm glad this thread came up.
