lines() appears to have a similar affliction, though I don't see any difference 
if the number of lines is even.

    $ cat foo.txt 
    a
    b
    c
    
    $ perl6 -ne '@ = lines' foo.txt 
    readline requires an object with REPR MVMOSHandle
    in block <unit> at -e line 1
    
    
    $ perl6 -ne 'lines.eager' foo.txt 
    readline requires an object with REPR MVMOSHandle
    in block <unit> at -e line 1
